Blake's 7: Orac

A spaceship crashes approaching the planet Cephlon and when the crew of the Liberator answer the distress call they find their own lives endangered. Blake is caught in a desperate race against time to save the lives of the crew and also find the mysterious ORAC. Once in Blake's possession, ORAC predicts the future of Blake and his crew by showing them an image of the Liberator blown to atoms in space. Blake is powerless to alter their inevitable destruction, and when the Liberator is seized by a hostile force, a series of terrifying events sets the prophecy in motion.
