Doctor Who: The Armageddon Factor

The Armageddon Factor is the sixth and final serial of the 16th season of the British science fiction television series Doctor Who, which was first broadcast in six weekly parts on BBC1 from 20 January to 24 February 1979.

Searching for the final segment of the Key to Time, the Fourth Doctor and Romana arrive on the planet Atrios, which has endured a recent bombing by their neighbouring planet Zeos, with whom they are at war. The Doctor finds that Zeos is deserted, its inhabitants possibly already annihilated, save for the giant computer Mentalis, which is controlling the outcome of the war.

He also discovers that the true opponent is a third space-station-like planet called the Planet of Evil, ruled by "the Shadow". The Shadow, an agent of the Black Guardian, has Princess Astra of Atrios captive, threatening to torture her if she doesn't give him the location of the final segment of the Key to Time.

On the Planet of Evil, the Doctor encounters another Time Lord, Drax, who he last met at the Academy. Drax has been employed under duress by the Shadow but agrees to help the Doctor. The Doctor leads a servant of the Shadow, known as a Mute, to his TARDIS and opens the door, but is suddenly shrunk to tiny size by Drax, who then shrinks himself using the dimensional stabiliser from his own TARDIS. Drax had misinterpreted the Doctor's plan and shrank the Doctor instead of the Mute.

The Mute returns to the Shadow with the Key, and the Doctor realises why the Shadow has requested it: Astra is the final segment, and is transformed in front of everyone. Using their diminished size, the Doctor and Drax smuggle themselves into the Shadow's lair inside of K9, who pretends to still be under the Shadow's power.

Drax again uses the stabiliser, this time to return them to their normal size. The Doctor snatches the partially assembled Key and the final segment, and disappears with Romana and K9 in the TARDIS, assembling the Key after setting up a shield around Zeos to deflect the Marshal's missiles towards the Shadow's base, destroying it.

The White Guardian appears to congratulate the Doctor on finding and assembling the Key to Time, and requests that it be sent to him. However, the Doctor, catching onto the Guardian's blatant disregard for Astra's sacrifice, realises that it is actually the Black Guardian in disguise, and orders the Key to re-disperse, restoring Astra to life.

Enraged, the Black Guardian threatens to kill him. In an attempt to evade him, the Doctor fits a randomiser into the TARDIS guidance system, sending it to an unknown location in time and space, leaving the Doctor with no idea of where they are headed, and the Guardian being unable to follow.
