Doctor Who: Earthshock

The TARDIS visits the planet Deva Loka, where Nyssa remains behind in the ship to recover from a mild mental disorientation while the Doctor, Tegan and Adric explore. Tegan falls asleep under some wind chimes and becomes possessed by an evil force, a Mara.

The Doctor goes to Logopolis to repair the TARDIS' chameleon circuit, not knowing that a shadowy watcher is spying on him. Meanwhile, his old enemy the Master has only recently gained secure longevity by possessing the body of Tremas, and revels in his safety. He has plans of his own for the planet of mathematicians, Logopolis, and a plan that could spell doom for the entire universe. The Master's plan could rock Logopolis, the keystone of all life. Could this mean the unravelling of the causal nexus and the end of the universe itself? The Doctor must pit his wits against the Master in a desperate battle to thwart his plans. But he is aware that this might be a fight which could easily spell the end of his life.

The Omega Factor is a British television series produced by BBC Scotland in 1979. It was created by Jack Gerson and produced by George Gallaccio, and transmitted in ten weekly episodes between 13 June and 15 August.

Dramarama is the name of a British children's anthology series broadcast on ITV between 1983 and 1989. It tended to feature drama of a science fiction or supernatural bent. The series was created by Anna Home, then head of children's and youth programming at TVS, however production responsibilities were divided amongst most of the regional ITV franchise holders. Thus, each episode was in practice a one-off production with its own cast and crew, up to and including the executive producer. Dramarama was largely a place for new talent to prove themselves and was a launching pad for the likes of Anthony Horowitz, Paul Abbott, Kay Mellor, Janice Hally, Tony Kearney, David Tennant and Ann Marie Di Mambro. It was one of Dennis Spooner's last credits. One of Dramarama's episodes, "Dodger, Bonzo And The Rest", gained so much popularity that it was turned in to its own series the following year. It starred Lee Ross and was based around a large foster home. The episode "Blackbird Singing In The Dead of Night" was developed by Granada into the TV series Children's Ward. It was also repeated for the first time since its original broadcast on 5 January 2013, during CITV's 30th anniversary Old Skool Weekend. The Series 7 episode "Back To Front" – notable for featuring a mirror image of the Yorkshire Television logo card at the end – was repeated on 6 January 2013, again as part of CITV's 30th anniversary Old Skool Weekend.

The TARDIS falls through a CVE into E-Space and arrives on the planet Alzarius. There the inhabitants of a crashed starliner and a group of young rebels called the Outlers, led by a boy named Varsh and including his brother Adric, are terrorised by a race of Marshmen who emerge from the marshes at a time known as Mistfall. The Doctor discovers that the starliner's inhabitants are not the descendants of its original crew, as claimed by their leaders, the Deciders, but evolved Marshmen. With the Time Lord's help and encouragement, the starliner is repaired and able to leave the planet.
