Brian (Ryan Sampson) and Gemma (Cassie Layton) are trained to pass themselves off as convincing Martians, without much success in Brian’s case. Meanwhile, Jenkins (John Sessions) and Troy (Freddie Fox) have all the water removed from their bodies by the pig dehydration device, and hide in Guuuurk’s (Kevin Eldon) pocket.

The crew infiltrate the Martian Invasion Vessel, but Guuuurk hasn’t counted on meeting an old friend aboard, who may not be as trustworthy as he seems. And isn’t.

Back in the Lab, the Professor (James Fleet) works on the bomb-melting ray, with a little help from half a brain in a diving suit (Rachel Atkins).

The plan is on target, up until the moment Gemma steps into the Martian Deep-Memory-Guilt-Testing ray, and is rendered frozen by a terrible, long-buried secret.
