  Gamekeeper Ollis 
            vanishes after finding a weather balloon with equipment belonging to 
            Dr. Tyler, a research physicist. Tyler gets in touch with UNIT, 
            something he'd intended to do because of his tests, which show an 
            unknown form of cosmic radiation. While The Doctor and Jo 
            investigate, Tyler vanishes from The Doctor's lab. When Jo and The 
            Doctor return, they're attacked by an energy form which apparently 
            consumes Bessie. The Doctor realizes that Tyler was taken because he 
            was in the lab, and that he is the being's intended target. UNIT HQ 
            is attacked by gel creatures, and the Brigadier orders the building 
            evacuated. The Doctor, Jo, and Sgt. Benton are trapped in the lab, 
            and The Doctor ushers them into the TARDIS. The Doctor sends an 
            emergency call to the Time Lords, who have their own problems. Their 
            energy is being drained through a black hole, and they're unable to 
            assist The Doctor directly. The Lord President decides to let The 
            Doctor help himself, and orders that The Second Doctor be lifted out 
            of his timeline (The Krotons). The 
            Third Doctor finds a recorder on the TARDIS console, which is 
            plucked from his hand by his predecessor, who's delighted to see his 
            old friend Benton. The Doctors link minds so The Second Doctor can 
            learn the situation, and the two begin to bicker about how to 
            proceed. The President decides to retrieve The First Doctor (The Massacre) to mediate, but can't 
            arrange a complete transfer. This Doctor is suspended in the time 
            vortex in a protective bubble, and his communication with his later 
            selves (whom he refers to as "a dandy and a clown") is limited. He advises them that the 
            organism is a bridge to another dimension, and The Third Doctor 
            decides to use it. Jo tags along, and they vanish. The Brig is 
            surprised to see The Second Doctor, but is more concerned with 
            finding a way to stop the creatures.  The Third Doctor and Jo arrive in a bleak 
            landscape, find Bessie and Tyler, and are captured by the gel 
            guards. The Second Doctor's attempts to calm the organism fail, and 
            he, Benton, and the Brig retreat to the TARDIS, where he discovers 
            that his recorder is missing. The First Doctor advises him to turn 
            off the TARDIS's force field, and the ship and UNIT HQ are 
            transferred through the black hole. Jo and Tyler are locked up, and 
            The Doctor taken to their captor, Omega, the legendary engineer who 
            gave the Gallifreyans the power to travel in time. Omega has been 
            trapped for millennia in the anti-matter dimension, which he 
            controls by force of will. Omega captures the new arrivals, but the 
            Brig evades the guards and finds Ollis. Omega is angry to learn that 
            he's captured two incarnations of The Doctor, and imprisons them. 
            The Doctors pool their mental power to escape, and go to the 
            singularity chamber which connects to the positive matter universe. 
            The others escape from Omega's lair, find the Brig and Ollis, and 
            head for UNIT HQ. Omega finds the Doctors, and angrily forces The 
            Third Doctor to engage in mental combat. After he releases The 
            Doctor, he explains that he's trapped in this dimension. Omega 
            cannot leave unless he abandons control, and if he does so the 
            dimension will collapse. He wants the Doctors to take his place. 
            They discover that Omega's physical form has been destroyed, and 
            that he is a being of pure will, who can never leave the anti-matter 
            universe. They escape while he's dealing with this revelation, and 
            return  to UNIT HQ. Along the way, they have an encounter with a creature called 
            the Ergon, which The Doctor later refers to as one of Omega's less 
            successful experiments (Arc of Infinity). They confer with The First Doctor, and realize 
            they can use the TARDIS's force field generator to destroy Omega. 
            The Second Doctor's recorder has become lodged in the generator. 
            Omega allows The Doctor to move the TARDIS to his palace, and The 
            Doctors convince him to let their friends return to Earth through 
            the singularity chamber. The Doctors offer him the generator and 
            recorder, but Omega angrily knocks them aside, triggering an energy 
            surge. The Doctors flee in the TARDIS, and are returned to Earth, 
            along with UNIT HQ. The energy creates a supernova which provides 
            the Time Lords with a new power source. The earlier Doctors are 
            returned to their own timelines. The Third Doctor explains that the 
            recorder wasn't converted to anti-matter when the TARDIS came to 
            Omega's realm, and the collision of matter and anti-matter caused 
            the energy surge. He regrets tricking Omega, who was one of his 
            childhood heroes. A new dematerialization circuit appears on the 
            TARDIS console, and The Doctor's knowledge of time travel theory 
            returns. The Time Lords have ended his exile, but much work remains 
            to be done to get the TARDIS in working order.

          | Location: Inter Minor | Date: Unknown |  
          | The Doctor 
            tries to take Jo to the beautiful planet Metebelis 3 to celebrate 
            the return of his freedom, but the TARDIS materializes in the hold 
            of the S.S. Bernice, which vanished from the Indian Ocean in 
            1926. The ship is attacked by a dinosaur, and the travelers soon 
            learn that its crew and passengers are repeating the same sequence 
            of events. The Doctor discovers that a deck hatch, which the crew 
            can't see, is held with anti-magnetic cohesion. The Doctor and Jo 
            retrieve a device from the TARDIS to open the hatch. As they leave 
            the hold, a giant hand comes through the ceiling and takes the 
            TARDIS away. When The Doctor opens the hatch, he discovers they're 
            inside a giant machine. He cuts through a wall, and he and Jo enter 
            a cave, which leads to a swamp inhabited by ravenous monsters The 
            Doctor identifies as Drashigs. The Doctor realizes that he and Jo 
            are inside a miniscope, a device used to store miniaturized 
            specimens, which The Doctor convinced the High Council to ban. Jo is 
            captured by the crew, but The Doctor escapes from the miniscope and 
            returns to his full size. The
  Doctor learns that the scope belongs to a Lurman 
            showman named Vorg, who is being held for questioning, with his 
            assistant Shirna, by a tribunal of the planet Inter Minor. Two of 
            the tribunal members plan to use the Drashigs to destroy their 
            ruler. The Doctor intends to rescue Jo and the others by linking the 
            scope to the TARDIS. After he builds the link, he returns to the 
            scope to find Jo. The miniscope fails, and a Drashig escapes and 
            kills a tribunal member. Vorg destroys the other Drashigs and 
            operates The Doctor's device, restoring the scope's inhabitants to 
            their proper places (since the Bernice was recorded as lost, 
            it's likely that something happened after its return which kept it 
            from reaching port). The miniscope is destroyed, and The Doctor and 
            Jo leave, as Vorg tries another way of making a profit from the 
            natives of Inter Minor.

          | Frontier in Space |  
          | Locations: See below | Date: 26th Century |  
          | The TARDIS 
            nearly collides with a freighter in hyperspace, but The Doctor 
            materializes it inside the ship, which is attacked by what seems to 
            be a Draconian cruiser. Jo believes that the ship's pilot is a 
            Drashig, and he sees Jo and The Doctor as Draconians. They are taken 
            hostage, and the ship is
  boarded by Ogrons, who steal its cargo and the TARDIS. The 
            Doctor and Jo are transferred to an Earth battle cruiser, and are 
            taken to Earth. The Doctor tries to convince Earth's president of 
            their innocence, but her military commander, General Williams (who 
            has fought Draconians before), refuses to believe him. There have 
            been several attacks on Earth ships by Draconian cruisers, but the 
            Draconians insist their ships are being attacked by Earth forces. 
            The Prince of Draconia captures The Doctor, but he too does not 
            believe the stories of hallucinatory enemies. The Doctor is 
            recaptured by Earth troops, and is imprisoned on the Moon. Jo learns 
            that The Master, who claims to be a commissioner from an Earth 
            colony with a prior claim on The Doctor and Jo, is behind the 
            attacks. The President agrees to turn them over to him, and after he 
            retrieves The Doctor, they leave in his prison ship. The ship is 
            captured by Draconians, but The Master sends a signal to his Ogron 
            allies. The Doctor, who informs the Draconian emperor that one of 
            his predecessors knighted The Doctor some 500 years before, attempts 
            to convince him of what The Master is doing. The emperor's court is 
            attacked, apparently by humans, and The Master is rescued. The 
            Emperor believes The Doctor's story when he sees a captured "human" 
            revert to Ogron form, and he sends The Doctor, Jo, and the Prince to 
            warn Earth. They are attacked by The Master, and a docking party of 
            Ogrons captures Jo. The others are rescued by an Earth cruiser, and 
            Williams, who's learned that what he believed to be an act of 
            treachery by the Draconians in the last war was the result of 
            misinformation, accompanies them in pursuit of The Master, who has 
            fled to the Ogron homeworld. The Master unsuccessfully tries to 
            hypnotize Jo, and she's also able to overcome the effects of the 
            device which causes the illusions. She escapes from her cell, and 
            transmits a message which is intercepted by the ship carrying The 
            Doctor and his allies. Jo soon learns that this was all a ruse by 
            The Master, who wants The Doctor to find him. After being attacked 
            by Draconians, The Doctor's ship arrives on the Ogron world. The 
            group are attacked by Ogrons, who are frightened away by the 
            appearance of a monstrous creature they regard as a god. The Master 
            appears with his other allies, a squad of Daleks, who capture The 
            Doctor, Williams, and the Prince. The Daleks leave the prisoners 
            with The Master. Jo has stolen the illusion device, which The Doctor 
            uses to convince their Ogron guard that they are actually Daleks, 
            and the guard frees them. The Prince and the general escape, and The 
            Doctor and Jo head for the TARDIS, which has been brought to the 
            planet. They encounter The Master and a squad of Ogrons, and in the 
            ensuing scuffle The Doctor is shot by The Master. Jo and The Doctor 
            get into the TARDIS, and as the ship dematerializes The Doctor sends 
            a message to the Time Lords.

          | Location: Spiridon | Date: 26th Century |  
          | 
  The Doctor collapses as 
            the TARDIS materializes on Spiridon. Jo leaves to get help, and the 
            ship is engulfed in a fungus which drains its oxygen supply. Jo 
            enters a crashed spaceship and is found by two Thals, Taron and 
            Vaber. When they are called away by a third Thal, Codal, she hides 
            in a storage hold and observes as an invisible creature explores the 
            ship. The Doctor has recovered, and is rescued by the Thals, who 
            remove the fungus from the TARDIS. Jo is befriended by one of the 
            invisible creatures, called Spiridons. The Doctor and the Thals 
            discover that the Daleks are trying to learn the secret of 
            invisibility, and he and Codal are captured. The other Thals debate 
            the merits of blowing up the Daleks' base, but are interrupted by 
            the crash of another Thal ship which was sent to rescue them. One of 
            its crew warns them that an army of 10,000 Daleks is hidden on the 
            planet. The Thals discover that Spiridon's interior contains a 
            bizarre form of liquid ice, which can erupt from "ice volcanoes". 
            The Doctor and Codal have escaped, and rescue the others from one of 
            these eruptions. The Doctor discovers that the Dalek army is in 
            suspended animation in an ice cave. Jo's Spiridon friend sacrifices 
            himself to prevent the Daleks from releasing a bacteria which will 
            kill all other life on the planet. After a series of escapes from 
            the Daleks in which several Thals are killed, The Doctor and the 
            others enter the Dalek city, where The Doctor intends to use the 
            cave's temperature controls to seal the Dalek army in ice forever. 
            He is thwarted by the Dalek Supreme, who's arrived to take charge of 
            the operation. The Doctor then uses a Thal bomb to activate an ice 
            volcano which traps the Dalek army and destroys the other Daleks. 
            One of the Thals, Latep, has fallen in love with Jo and asks her to 
            go to Skaro with him, but she refuses, and the Thals leave. The 
            Doctor and Jo return to the TARDIS, pursued by the Dalek Supreme, 
            who fails to prevent their escape.

          | The Green Death |  
          | Locations: UNIT HQ, Wales, Metebelis 3 | Date: 1973 |  
          | 
  In the Welsh village of Llanfairfach, mines are closed by 
            Global Chemicals, and the miners are protesting. A miner is found 
            dead, his skin glowing green. UNIT is called to investigate, and to 
            provide protection for Global, whose owner, Stevens, has powerful 
            friends in the government. Global's activities are also coming under 
            fire from Professor Clifford Jones, a Nobel Prize winner whose 
            commune of scientists, called the Nuthatch by the locals, is 
            investigating pollution caused by the company. Jo plans to go to 
            Wales to join Jones, and refuses to help the Brig, who still allows 
            her to travel there with him. The Doctor, disappointed by Jo's 
            refusal to try another visit to Metebelis 3, goes alone, arriving in 
            the wrong time period, and is attacked by the planet's inhabitants. 
            He escapes, and brings back a blue crystal as a souvenir. Stevens 
            maintains that Global's processes are non-polluting, but Jones 
            disagrees. Jo investigates the mine, which she thinks is being used 
            to dump the pollutants. She is aided by some of the miners, one of 
            whom, Bert, is exposed to the chemical which killed the other miner. 
            They're trapped in the mine when its sabotaged lift breaks down. 
            Stevens, under orders from a mysterious BOSS, refuses the Brig's 
            request to help rescue them, falsely claiming that Global does not 
            have the equipment. While The Doctor and the Brig look for other 
            equipment, Jo and Bert explore. Bert's condition worsens, and Jo 
            proceeds alone. She finds a pool of green slime, which is infested 
            with giant maggot-like creatures. The Doctor and another miner find 
            Bert, who's taken back to the surface. The Doctor tracks down Jo, 
            but they're trapped when a section of the roof collapses. They 
            escape via a shaft which leads into Global's complex. At the 
            Nuthatch, The Doctor observes that Jo is attracted to Professor 
            Jones. He also sees that the scientists use the local fungus as 
            food. After another maggot sighting, the Brigadier decides to seal 
            the mines. Stevens receives a visitor from the government, who's 
            actually Captain Yates, working undercover. Although the mine is 
            sealed, the maggots find other routes to the surface, and they're 
            impervious to conventional weapons. The Doctor decides that a 
            biological weapon is needed, and breaks into Global to steal some 
            oil waste, disguising himself as a milkman to infiltrate the 
            complex, and then assuming the guise of a cleaning lady. He 
            encounters an amused Yates, who tells him that there is a special 
            lift, used only by Stevens, to the top floor. Jo, meanwhile, has 
            spilled fungus powder on one of Cliff's slides, and attempts to make 
            it up to him by capturing a maggot for study. Cliff finds that Jo's 
            accident has shown him that the fungus neutralizes the infection, 
            and may be a clue to the end of the menace. He finds Jo, but they 
            are trapped in a cave when the RAF, who've been called in by the 
            Brig, bomb the maggot swarm. The Doctor discovers that BOSS is a 
            sentient computer which controls Stevens. The machine can't control 
            The Doctor, and he escapes with help from Yates, who's captured. The 
            Doctor and Sgt. Benton rescue Jo and the infected Cliff, who 
            deliriously repeats the word "serendipity". Yates arrives, under 
            control, and pulls a gun on The Doctor, who uses his blue crystal to 
            free Mike from hypnosis. Yates returns to Global with the crystal, 
            and after freeing one of Stevens' aides, discovers when BOSS's plan 
            will take effect. While The Doctor continues to look for a solution, 
            a commune member discovers that a maggot has died after eating 
            fungus. The Doctor and Benton drive Bessie through the maggots, 
            using the fungus to kill them. Back at the Nuthatch, The Doctor 
            tells Jo that "serendipity" means "a happy accident" and she 
            explains how she spilled the powder on Cliff's slides. The Doctor 
            realizes that the fungus will cure the infection as well. After 
            making sure that Cliff will be all right, he returns to Global, 
            where he uses the blue crystal to free Stevens from BOSS's control. 
            Stevens activates the computer's self-destruct sequence, and The 
            Doctor escapes from the complex before it explodes. Back at the 
            Nuthatch, Jo tells The Doctor that she has fallen in love with 
            Cliff, who reminds her of The Doctor in many ways. She intends to 
            marry him, and plans to use an expedition to the Amazon, arranged by 
            the uncle who got her the UNIT job, as a honeymoon. The Doctor is 
            saddened by her decision, but gives Jo the crystal as a wedding 
            present. As the members of UNIT and the Nuthatch congratulate the 
            happy couple, The Doctor slips out into the night and drives away in 
            Bessie.

  Several prominent scientists disappear, and the 
            Brig, who's arranged a secure facility for others, asks The Doctor 
            to investigate. The Doctor meets journalist Sarah Jane Smith, who's 
            infiltrated the facility by impersonating her Aunt Lavinia, an 
            eminent virologist. The Doctor thinks the scientists have been taken 
            through time, and sets up sensors to detect temporal disturbances. 
            Another scientist, Rubeish, disappears, and when The Doctor uses his 
            sensors he sees the ghostly traces of a Sontaran warrior. He follows 
            the Sontaran in the TARDIS, unaware that Sarah, who thinks The 
            Doctor is the villain, is in the ship. Sarah leaves the TARDIS after 
            The Doctor's departure, and prevents an archer named Hal from 
            shooting Irongron, the local robber baron. They're captured, and 
            Sarah initially believes that she's been transported to an elaborate 
            medieval theme park. She's questioned by the Sontaran, Linx, who 
            soon realizes that she is a time traveler. Linx has crashed his ship 
            near Irongron's castle, which he's using as a base while he makes 
            repairs. He's providing weapons for the baron, and has kidnapped the 
            scientists because Irongron's people aren't advanced enough to help 
            him. He gives Irongron a fighting robot, which he tests against Hal, 
            but The Doctor shoots the control from Irongron's hand, and the 
            archer and Sarah escape from the castle in the confusion. The Doctor 
            finds the scientists, and learns that they've been hypnotized, 
            except for the near-sighted Rubeish. Linx appears and takes The 
            Doctor prisoner, after refusing his offer of assistance.  Rubeish releases The Doctor after Linx departs. Sarah, 
            meanwhile, has met Hal's lord, Edward of Wessex, and convinced him 
            to send men to kidnap The Doctor. Once The Doctor is brought to 
            Edward's castle he convinces him, and Sarah, of his good intentions, 
            and with the use of dummies, and smoke and stink bombs, helps defend 
            the castle from an assault by Irongron. The Doctor proposes that 
            they go on the offensive, and asks Edward's wife, Lady Eleanor, for 
            ingredients to make a sleeping potion. He and Sarah disguise 
            themselves as monks, and while The Doctor assists the scientists, 
            Sarah slips the potion into the castle's evening meal. The Doctor 
            uses his penlight to break the trance in which the scientists have 
            been placed, and when Linx returns, he distracts him while Rubeish 
            hits him in the probic vent at the back of his neck, a hole through 
            which Sontarans ingest energy, and their only weak spot. The Doctor 
            trusses up the Sontaran, and disguises himself as the robot to 
            distract Irongron. The robber baron sees through the disguise, but 
            The Doctor is rescued by Sarah, and they return to Edward's castle, 
            intending to go back after the sleeping potion has time to work. 
            Linx escapes from his bonds and begins his countdown. The Doctor 
            returns to Irongron's castle with Sarah and Hal, and uses Linx's 
            equipment to return the scientists to their own time. Hal is sent to 
            wake up Irongron's men so they can flee the castle, which will be 
            destroyed when the Sontaran ship takes off. Irongron has already 
            awakened and confronts Linx, who kills him before he enters his 
            ship. Hal returns to the workshop, and kills Linx by firing an arrow 
            into his probic vent. The Doctor is unable to abort the countdown, 
            and he, Sarah, and Hal escape from the castle just before it 
            explodes.
