Episode Details
Still unstable from his regeneration, the Doctor is spending much of his
time in the UNIT sick bay. Sarah-Jane decides to use the opportunity to
investigate a top secret government Think-Tank.
She becomes suspicious that all is not as it should be and that a large
Robot under the control of the Think-Tank is responsible for a number of
break-ins at top secret military bases.
"Computers are very sophisticated idiots."
- Doctor, ROBOT
The Doctor, Sarah and Harry arrive on a deserted space station in the
distant future.
They discover that it contains the entire population of Earth in hibernation
who have not reawakened when they should have done because of a fault in
the computer.
In the meantime, the station has been invaded by the Wirrn, a large insect
like animal who have other plans for the sleeping humans...
"Judging by the size of its mandibles, this chap doesn't live on plankton."
- Harry Sullivan, ARK IN SPACE
Transported back to Earth of the distant future from the Ark, the Doctor
Harry, and Sarah discover that they have unwelcome company -

The warrior is involved in deadly experiments to assess the human race as
an adversary prior to a full scale invasion of Earth.
