In 1972 Mason Skiles (John Hamm) works as a US diplomat in Lebanon living in Beirut married to his Lebanese wife, Nadia. The couple was taking care of Karim a 13-year-old who claims he doesn't have a family. Surprisingly, the US government discovers that wasn't true, Karim is linked to a brother who was part of the 1972 Summer Olympics Massacre in Munich. During a celebration at Mason's house, Karim is abducted by his brother and Nadia is murdered.

10 years later, Skiles is living in the US, doing work as a labor arbitrator, he is now alcoholic and depressed, the US government needs him, to rescue an old friend Gary Ruzak (Shea Whigham). The team who brought Skiles back is Sandy Crowder (Rosamund Pike) Donald Gaines (Dean Norris) and Frank Whalen (Larry Pine).

Skiles biggest revelations are how much Beirut has changed for the worst. The city was vibrant, filled with life and so much money pouring from all over the world, now is a war zone.
