This is based on the 2021 book The Lockerbie Bombing: A Father's Search for Justice by Jim Swire and Peter Biddulph.
"In December 1988, Pan Am Flight 103, a transatlantic flight from London to New York City, was destroyed by a bomb 38 minutes after take-off while flying over the Scottish town of Lockerbie, killing all 243 passengers and 16 crew members. Parts of the aircraft crashed into a residential area, killing an additional 11 people. The series will follow the true life story of Jim Swire (Firth) and his wife Jane in their quest for justice for the victims, who included their daughter Flora."
Pan Am Flight 103 (PA103/PAA103) was a regularly scheduled Pan Am transatlantic flight from Frankfurt to Detroit via a stopover in London and another in New York City. Shortly after 19:00 on 21 December 1988, while the Boeing 747 "Clipper Maid of the Seas" was in flight over the Scottish town of Lockerbie, it was destroyed by a bomb, killing all 243 passengers and 16 crew in what became known as the Lockerbie bombing. Large sections of the aircraft crashed in a residential street in Lockerbie, killing 11 residents. With a total of 270 fatalities, it is the deadliest terrorist attack in the history of the United Kingdom. (Wikipedia)
