Blake's 7: The Beginning (1978)

Edited from the first four episodes of the cult 1978 BBC TV series set in the far future where freedom fighter Roj Blake, framed by the all-powerful but corrupt Galactic Federation which runs all human affairs, escapes his captors from his sentence to a harsh penal colony and, helped by a handful of fellow convicts and armed with a superbly-equipped alien spaceship, sets about restoring freedom to the galaxy.
