Episode Details

Terror of the Zygons

The Brigadier summons the Doctor back to Earth using a time/space telegraph device the Doctor left with him for grave emergencies. There has been a spate of disappearances, sinkings and attacks on oil rigs in the North Sea under very mysterious circumstances. The Doctor soon discovers that an unknown force is controlling the Loch Ness monster and has turned it from a shy, placid creature into a weapon of destruction...

Planet of Evil

The Doctor and Sarah-Jane arrive on the planet Zeta minor at the very edge of the Galaxy in answer to a distress call. All but one of a geological survey party from Morestra have been sucked dry by an invisible monster. A rescue ship arrives from Morestra but will the mysterious forces that control the planet allow anyone to leave...

Pyramids of Mars

The excavation of an ancient Egyptian tomb unleases the Evil Sutekh, last of the Osirans, imprisoned millenia before by his own people. Sutekh attempts to build a time/space bridge between his tomb prison and the English manor house that was the home of the unfortunate archeologist who opened the tomb.

The Android Invasion

Returning back to what appears to be UNIT headquarters, the Doctor and Sarah discover that all is not quite as it seems and that all their old friends are, in fact, Androids.

"This isn't Earth. This isn't real wood, it's some kind of artificial material, like plastic. These aren't real trees, and you're not the real Sarah!" - Doctor, THE ANDROID INVASION

The Brain of Morbius

Landing on a barren and stormy planet, the Doctor and Sarah seek refuge in home of a scientist who appears to be trying some rather sinister experiments.

"There's something going on here. Some dirty work that they won't touch with their lily-white hands."
- Doctor, THE BRAIN OF MORBIUS

"The Time Lords are spineless parasites. Morbius offered them greatness once, but he was betrayed and rejected. They'll pay for that mistake, Condo. Those pacifist degenerates will be the first to feel the power of his revenge."
- Solon, THE BRAIN OF MORBIUS

"I know the Time Lords: pallid, devious worms."
- Morbius, THE BRAIN OF MORBIUS

The Seeds of Doom

When an alien seed pod is discovered buried in glacial ice, a wealthy botanist arranges to have it stolen. Soon it starts to germinate and turns out to be very dangerous.

"And what is your bureau doing about bonsai?"
- Harrison Chase, THE SEEDS OF DOOM

"The plants must win. It will be a new world, silent and beautiful."
- Harrison Chase, THE SEEDS OF DOOM
