The music was used in trailers and later commercially released, reaching the top five of Irish and British singles charts, bringing the band its first major international exposure.

The British government cabinet minister Henry Danby is killed by an IRA gunman, Billy Downes, in front of his wife and children outside his home in London.

Given the cover identity of merchant seaman Harry McEvoy, he finds lodgings in the Falls Road area and secures a job in a scrapyard.

Harry tips off his superiors that the killer was at the club and that Theresa, a girl at whose family home Billy stayed the night while on the run, knows his name.

The series closes with a narrator reading a part of a poem written by the daughter of real-life IRA victim William J. Staunton, a 46-year-old magistrate shot dead in 1973: "Don't cry, Mummy said.

The rest of footage, filmed in Ireland, include shots of the Falls Road, broader views as where Harry is frisked on entry to Belfast city centre (there was a permanent checkpoint for pedestrians there for many years) and the final scenes overlooking the cityscape were in Holywood, County Down and close to the military/MI5 barracks.
