Shake and Blake - Episode 15

Dave and Ian embark upon season three of Blake's 7. In "Aftermath,"
after battling an armada trying to invade the galaxy, the crew
abandons a badly damaged Liberator, and Avon meets new allies and
an old enemy. In "Powerplay," Avon finds the Liberator occupied by
Federation troops. He and Dayna must find a murderer and retake the
ship while Vila and Cally are cared for by people who aren't as
benevolent as they appear. The boys from Britain also discuss new
members of the crew, debate what is "The Web" of Star Trek, and
which of the episodes discussed is an allegory for Britain's
current government.
