Blake's 7

A rebel leader, his memory altered by an oppressive galactic government, suffers injustice after witnessing a massacre.

Blake and some criminals attempt to seize control of the prison ship London as it passes a space war where an abandoned ship is found.

Blake tries to rescue the remaining prisoners from the prison planet Cygnus Alpha only to find they have a disease that can be cured by the power mad high priest Vargas.

A ship whose crew had been put in suspended animation is picked up by the Liberator, while Blake attempts to destroy the Federation Communication base on Saurian Major.

The Liberator runs into a web created by psionic means; the crew meets the race of genetically-engineered Decimas. Blake learns of the attempt at genocide being waged against the Decimas by the creator of the Web.
