STORY:

The TARDIS lands on the planet Oseidon where a species known as the Kraals have created an exact replica of Earth. It is son life-like that the Doctor and Sarah have no idea they are not on Earth.

As they are walking around they notice a U.N.I.T. soldier stumbling towards a cliff, then plunge over the edge. They later see the same man in a pub.

The Doctor discovers that they are not on Earth, and that a human astronaut, Guy Crayford, has been assisting the Kraals. The Kraals plan to release a deadly virus on Earth, and are going to use the spaceship of Crawford to spearhead the invasion.

On Earth the Doctor and Sarah try to alert the troops at the Space Defence Centre of the danger. With the Brigadier in Geneva the warning goes unheeded.

The Doctor uses the centre's radars to jam the signals of the androids activated on Earth, and Styggron, leader of the Kraals, falls victim to his own poison.
