Blake's 7 is a British science fiction television series made by the British Broadcasting Corporation (BBC) for their BBC 1 channel. Created by Terry Nation, a prolific television writer best known for creating the popular Dalek monsters for the television series Doctor Who, it ran for four series between 1978 and 1981. Popular from the time it was first broadcast, it remains well regarded[1] on account of its dark tone, moral ambiguity and strong characterisation. It is also remembered for the shock ending that concluded the series. Set in the "third century of the second calendar",[2]Blake's 7 follows the exploits of revolutionary Roj Blake as he leads his band of rebels against the forces of the totalitarian Terran Federation which rules the Earth and many of the planets of the galaxy. The Federation controls its citizens by means of mass surveillance, brainwashing, and pacification with drugged food, water and air. Sentenced to deportation to a penal colony on a remote planet, Blake escapes with the help of his fellow prisoners and gains control of the Liberator, an alien spacecraft far in advance of anything the Federation possesses. The craft has superior speed and weaponry and a teleport system that allows crew members to be transported to the surface of a planet without having to land the ship. Blake and his crew then attempt to disrupt and damage the Federation.
