Jon Hamm sure shows off his acting chops in this trailer for Beirut.

Here’s the premise: A U.S. diplomat (Hamm) flees Lebanon in 1972 after a tragic incident at his home. Ten years later, he is called back to war-torn Beirut by CIA operatives (Rosamund Pike) to negotiate for the life of a friend he left behind.

Watch the trailer!

Beirut opens April 13.
