Documentary investigating the massacre in West Belfast in August 1971, in which 11 people died when British troops opened fire on Catholic residents. The film presents evidence suggesting that, contrary to the claims of the army at the time, all of the victims were innocent and unarmed. The families of the dead accuse Britain's elite Parachute Regiment of carrying out the shootings, the same regiment which, less than six months later, was to shoot dead 13 unarmed people on what became known the world over as Bloody Sunday.
