Lockerbie

As the families of those on board flight Pan Am 103 learn that the passenger plane has crashed over Lockerbie, killing 270, a terrorism investigation tries to find out what happened while a rural Scottish community is left reeling.

In 1988, the bombing of Pan Am 103 killed 270 people in Lockerbie, Scotland. This gripping four-part series follows the tragedy, investigation, and lingering questions surrounding the attack.

The CIA hands over a Libyan double agent who provides crucial evidence needed to bring the two bombing suspects to court, but the key witness changes his story as the trial gets underway.

The court makes a shock verdict that leaves the victims' families unsatisfied and casts doubt on the decision, but 34 years would pass since the bombing before the US apprehends a new suspect.
