Blake's 7
In the third century of the second calendar, a corrupt galactic federation, with Earth at its centre, Narcotises its billions of citizens into placid submission. A rebel named Roj Blake, who once tried to organise a resistance group to overthrow the regime, was caught and his memories wiped. But Blake's revolutionary spirit is revived when he witnesses a mass slaughter by police which is covered up by officials. He escapes on-board a prison ship, and together with a lovable band of outlaws, takes over a vacant alien space cruiser of awesome drive capability. Christening their ship, "The Liberator", Blake and his group travel the Milky Way to seek any opportunity to undermine the corrupt regime.
