          | The Claws of Axos |  
          | Location: England | Date: Early 1971 |  
          | UNIT is 
            visited by Chinn, a government minister, and Bill Filer, an American 
            agent who's investigating The Master. Radar shows a spacecraft 
            approaching Earth, which disappears before it can be hit by 
            missiles. It lands near the Nuton Power Complex. Filer arrives ahead 
            of UNIT, is captured, and finds The Master is also a prisoner on the 
            ship. The Doctor, the Brig, Chinn, and others go aboard the ship and 
            meet the Axons, a lovely race of humanoids who wish to replenish the 
            craft's energy, and offer axonite, a substance
  which mimics other elements, in exchange. The Doctor 
            points out that with this miracle substance they shouldn't have run 
            out of fuel, but is overridden by Chinn, who wants Britain to have a 
            monopoly on axonite. The Doctor wants to study the element, and has 
            the TARDIS brought to Nuton, hoping that the substance may give him 
            a way to escape his exile. The Axons free The Master so he can 
            arrange worldwide distribution of axonite, which will actually drain 
            Earth's energy. He's agreed to help them in exchange for his 
            freedom, and a chance to destroy The Doctor. While analyzing 
            axonite, The Doctor realizes the ship and the Axons are all parts of 
            a single organism which absorbs energy when it reaches lightspeed. 
            The Doctor and Jo are captured by the Axons, who force him to reveal 
            the theory of time travel. They overload the reactor to get power 
            for this, and the Brigadier must ask The Master for help. The Master 
            uses the TARDIS to absorb the energy, and when he uses the power to 
            attack the Axon ship, The Doctor and Jo escape. The Doctor 
            apparently teams up with The Master, and he offers to give time 
            travel to Axos in exchange for their promise to attack the Time 
            Lords. He links the TARDIS to Axos, and throws it into a time loop 
            as The Master escapes. The Doctor breaks out of the loop, leaving 
            Axos trapped, and admits to the Brig and Jo that he cannot escape 
            from Earth while the Time Lords' edict is in force.

          | Colony in Space |  
          | Locations: UNIT HQ, Exarius | Dates: 1971, 2472 |  
          | The Master 
            has stolen the Time Lords' data on the Doomsday Machine, and they 
            send The Doctor and Jo to Exarius, the planet where the device was 
            invented. They're soon caught up in a dispute between colonists, led 
            by Robert Ashe, and a group from the Interplanetary Mining 
            Corporation, whose operations will make the planet unfit for 
            agriculture. Complicating things are the planet's natives, the 
            Primitives, and attacks on colonists by giant lizards. The Doctor 
            learns that these are being faked by IMC's crew. Ashe and Captain 
            Dent of IMC have called in an Adjudicator from Earth to settle the 
            question of the planet's ownership. Jo is captured by Primitives and 
            The Doctor goes to their city, where he learns that they've 
            regressed from a powerful society into a culture which makes 
            sacrifices to a machine. The machine's Guardian, impressed by The 
            Doctor's intelligence, frees him and Jo. When they return to the 
            colony they find that The Master, posing as the Adjudicator, has 
            ruled in favor of IMC, and is trying to learn more about the 
            Primitives. The Master captures them, and forces The Doctor to take 
            him to the city. He explains that the Primitives built the Doomsday 
            Machine, and that the test which convinced them not to use it 
            created the Crab Nebula. He intends to use the device to hold the 
            galaxy hostage. The Guardian realizes The Master does not deserve 
            such power, and shows The Doctor how to destroy the machine. Ashe 
            sacrifices his life so the colonists can defeat the IMC group. The 
            Master escapes, and The Doctor and Jo return to UNIT HQ.

          | The Daemons |  
          | Location: England | Dates: April 30-May 1, 1971 |  
          | 
  On the night of the pagan festival Beltane, 
            Professor Horner plans to open an ancient barrow near Devil's End. 
            The Doctor and Jo see a broadcast in which the local white witch, 
            Miss Hawthorne, attempts to prevent the dig. The Doctor agrees with 
            her, and he and Jo head for the village, arriving too late to stop 
            Horner, who's killed by the energy released when the barrow is 
            opened. The Doctor has fallen into a coma, and Jo calls in Yates and 
            Benton, who fly to Devil's End after failing to reach the Brig. They 
            see giant hoof prints near the village. When The Doctor revives, he 
            discovers that a heat barrier surrounds Devil's End. He learns from 
            Miss Hawthorne that the new vicar, Mr. Magister, is involved in 
            these events, and he realizes that he is once again facing The 
            Master ("Magister" is Latin for "Master"). Jo and The Doctor go to 
            the barrow, and narrowly escape from a gargoyle after they find a 
            spaceship buried there. The Master intends to use its occupant, a 
            member of an ancient race called Daemons who inspired much of human 
            mythology, in his latest bid for power. The Daemon, Azal, is 
            considering The Master's request to pass on his power, but wants to 
            meet The Doctor so that he may decide which of the Time Lords 
            deserves this gift.  The Brigadier has arrived 
            with more troops, and The Doctor works with Sgt. Osgood to develop a 
            device to cut through the barrier. Villagers controlled by The 
            Master capture The Doctor as he returns to town, but he convinces 
            them to release him, thanks to some timely assistance from Miss 
            Hawthorne and Benton, who make it appear that The Doctor has magical 
            abilities. The Brigadier and his men have broken through the 
            barrier, and the device begins to drain Azal's power, but it 
            explodes when the power proves too great. Jo has been captured by 
            The Master, but is released by Azal when The Doctor arrives. The 
            Daemon has decided to give The Doctor his power, but offers it to 
            The Master when The Doctor refuses. Azal decides to kill The Doctor, 
            but Jo offers herself in his place, and the act of self-sacrifice 
            confuses the Daemon, who loses control of the power and destroys 
            himself and the village church. Benton finally succeeds in capturing 
            The Master, thanks to a remote control device which The Doctor has 
            installed in Bessie.

          | Unrecorded Events |  
          | Location: England | Date: Summer 1971 |  
          | The Doctor 
            continues to work on the TARDIS (Day of the Daleks). He also 
            testifies at The Master's trial, a proceeding closed to press and 
            public, and his eloquent defense of his old friend is largely 
            responsible for the tribunal's sentence of life imprisonment, 
            instead of the death penalty (The Sea Devils).

          | Day of the Daleks |  
          | Location: England | Dates: September 1971, alternate future |  
          | 
  The Doctor helps investigate an attack on Sir Reginald 
            Styles, host of the next peace conference. He learns that guerillas 
            from the future want to kill Styles, whom they hold responsible for 
            a bomb which destroyed the conference. This event created their 
            timeline, an alternate future in which the Daleks conquered Earth (a 
            century before the events of The Dalek Invasion of Earth). Jo 
            is transported to this future, and when The Doctor follows, he's 
            captured by Ogrons, the ape-like humanoid slaves of the Daleks. The 
            Daleks, who don't recognize The Doctor in this form, probe his mind, 
            and learn that he is indeed their greatest enemy. The Controller, 
            the human "ruler" of Earth, who has befriended Jo, convinces the 
            Daleks to let him interrogate The Doctor. Jo and The Doctor are 
            rescued by the guerillas, and he realizes the conference was 
            actually destroyed by one of the rebels. The Controller allows them 
            to escape back to the 20th century, and is exterminated by the 
            Daleks. The Doctor convinces The Brigadier to evacuate the diplomats 
            before the Daleks attack, and tells Shura, a rebel still in this 
            time, the truth about what is happening. Shura detonates his bomb, 
            destroying the Daleks and Ogrons, and the conference is saved.

          | The Curse of Peladon |  
          | Locations: UNIT HQ, Peladon | Dates: 1971, Unknown |  
          | 
  As The Doctor and Jo work 
            in the TARDIS, the Time Lords send the ship to Peladon, which has 
            applied for membership in the Galactic Federation. The Doctor is 
            mistaken for the Earth delegate, and he and Jo meet King Peladon, 
            and the other delegates, Alpha Centauri, Arcturus, and the Ice 
            Warrior Lord Izlyr and his aide Ssorg. The Doctor saves them from 
            being crushed by a statue of Aggedor, the sacred beast of Peladon's 
            legends. Arcturus is also attacked separately, but is rescued by The 
            Doctor. He suspects his old enemies, the Ice Warriors, of being 
            behind the attacks, but Jo discovers that they are innocent. During 
            his investigation The Doctor violates the Temple of Aggedor and is 
            sentenced to trial by combat with Grun, the King's champion. Hepesh, 
            the High Priest, offers to help The 
            Doctor escape, and gives him a map of the tunnels under the palace. 
            This leads The Doctor to the real Aggedor, but he hypnotizes the 
            beast with a Venusian lullaby and a spinning mirror attached to his 
            sonic screwdriver. The King does not believe that Aggedor is real 
            and orders the combat to proceed. The Doctor defeats Grun, sparing 
            his life, and Ssorg kills Arcturus, who was about to shoot The 
            Doctor. Hepesh, who had plotted with Arcturus, attempts a revolt, 
            but The Doctor brings Aggedor to the throne room and the creature 
            kills the traitorous priest. The Doctor and Jo leave just before the 
            real Earth delegate arrives.

          | The Sea Devils |  
          | Location: England | Date: 1972 |  
          | 
  The Doctor and Jo visit The Master in prison. 
            Trenchard, the prison governor, mentions that several ships have 
            sunk in the area, and The Doctor investigates. He's arrested and 
            taken to see Captain Hart at the naval base H.M.S. Seaspite. 
            Hart is convinced of his good intentions when Jo arrives with their 
            UNIT IDs. The Doctor and Jo visit a sea fort which he believes may 
            hold a clue to the sinkings, and they find a caretaker ranting about 
            Sea Devils. The Doctor encounters one of the creatures, which are 
            related to the Silurians, and drives it away. Back at the naval 
            base, Jo sees The Master dressed as a naval officer. They return to 
            the prison, where The Doctor learns that The Master has been using 
            Trenchard, and is stealing parts from the base to build a machine to 
            control the Sea Devils. Jo and The Doctor avoid capture by the 
            creatures. Hart has ordered a submarine to investigate the fort, but 
            it is disabled and captured by the Sea Devils. The Doctor goes down 
            in a diving bell, and he too is captured. The Master summons a group 
            of Sea Devils, who free him from prison and kill Trenchard. He 
            arrives at the reptiles' base and finds that The Doctor is 
            attempting to convince their leader to seek peace. This attempt is 
            ruined when the navy drops depth charges, but The Doctor escapes, 
            along with the sub's crew. The Sea Devils want The Master to revive 
            more of their people, and they recapture The Doctor when they attack 
            the naval base to get more electronic parts. The Master wants The 
            Doctor's help in reviving the creatures, but The Doctor sabotages 
            his device by reversing the polarity of the neutron flow. The Doctor 
            and The Master escape from the Sea Devils' lair just before it is 
            destroyed, and The Master steals a hovercraft and retains his 
            freedom.

          | The Mutants |  
          | Locations: UNIT HQ, Solos | Dates: 1972, 30th Century |  
          | The Time 
            Lords send a message container, a device which only opens for its 
            intended recipient, to The Doctor, and he and Jo use the TARDIS to 
            deliver it. They arrive on Skybase One, which orbits Solos. The 
            planet is about to be freed by the Earth Empire, a decision The 
            Marshal commanding the base disagrees with. He hates the Solonians 
            and plans to destroy them by altering the planet's atmosphere. The 
            Doctor discovers that the message is intended for Ky, leader of the 
            Solonian rebels. With the help of Professor Sondergaard, The Doctor 
            discovers that the Solonians undergo a natural mutation which the 
            Marshal's plan has accelerated. The Doctor prevents the planet's 
            atmosphere from being altered, and Ky, who has mutated into a 
            super-being, kills the Marshal.

          | The Time Monster |  
          | Locations: England, Atlantis | Dates: September 1972, circa 1500 BC |  
          | 
  The Doctor has a dream in 
            which he sees The Master with a crystal of power. When Jo wakes him 
            with news of volcanic eruptions near the site of Atlantis, he's 
            convinced the dream is a clue to The Master's latest plan. He builds 
            a device to trace his enemy, and turns down the Brig's invitation to 
            witness Professor Thascales' demonstration of TOMTIT (Transfer of 
            Matter Through Interstitial Time) at the Newton Institute. Thascales 
            is really The Master, who intends to use the device, powered by the 
            crystal, to control Kronos, one of the legendary Chronovores 
            (time-eaters). The Doctor tracks down The Master, and despite his 
            enemy's use of TOMTIT to create distractions, pursues him, 
            materializing his own TARDIS inside The Master's. (This also encases 
            The Master's TARDIS inside his own.) The Master frees his TARDIS, 
            and ejects The Doctor into the time vortex. The Doctor saves himself 
            (using his training in 
            vortex-walking: Shada) and 
            uses the TARDIS's telepathic circuits to tell Jo to activate the 
            ship's "extreme emergency" switch, which pulls him into the ship 
            (this is the use of the 
            ship's tractor beam "12 years ago" which The Fourth Doctor later 
            mentions to Romana: The Creature from the Pit). When The Doctor and Jo arrive in Atlantis, they 
            learn that The Master is attempting to gain power by romancing the 
            queen, Galleia. After a battle with a minotaur, they are imprisoned 
            in a dungeon, where the dying King Dalios begs The Doctor to save 
            his people. The Master has been crowned as king, but Galleia turns 
            against him when The Doctor reveals the villain's part in her 
            husband's death. Krasis, an Atlantean priest who's been coerced into 
            serving The Master, activates TOMTIT, and Kronos begins to destroy 
            Atlantis. The Master takes the crystal, intending to flee in his 
            TARDIS, and is attacked by Jo, whom he overpowers and takes along. 
            The Doctor follows, intending to use his own TARDIS to destroy The 
            Master's by Time Ram (a deliberate attempt to materialize a TARDIS 
            in the same co-ordinates as another TARDIS), but can't bring himself 
            to do so, since Jo will also die. Jo decides to make the sacrifice, 
            but the two time machines end up in a void, where the now-recovered 
            Kronos thanks The Doctor for her release. The Chronovore intends to 
            punish The Master, who escapes while The Doctor pleads with Kronos 
            to spare his enemy.
