30 years ago Britain's longest political trial ended at the Old Bailey with 10 year jail sentences for four young revolutionary anarchists.
They were members of the Angry Brigade; a clandestine urban guerrilla group who, for a few short years in the early 1970s, went on a bombing spree that brought terror to the heart of the British political establishment. Targets included senior Government ministers, captains of industry and top ranking policeman.
The Angry Brigade is a dramatised documentary which reconstructs the key moments and events of the time told through the eyes of one of the main members of the group.
The programme explores how these largely middle class students made the journey from hippie idealists to urban terrorists and the police investigation that finally cracked them.
