In 1988, the families of those on board flight Pan Am 103 learn that the plane has crashed over Lockerbie, Scotland, killing 270. A terrorism investigation begins.
The prime suspects for the bombing of flight Pan Am 103 are a Palestinian terror group funded by Iran. But Scottish and FBI investigators are led elsewhere.
A Libyan double agent provides the evidence needed to bring the two suspects to court. The trial gets underway, but a key witness changes his story.
A shock verdict leaves the families unsatisfied. Doubt is cast on the court's decision, and 34 years after the bombing, a new suspect is taken into US custody.
