During the Bosnian War, American troops witness atrocities and then shoot Serb soldiers they hold accountable for them.

n present-day Belgrade, Serbia, former Scorpions soldier Emil Kovač (Travolta), who survived the shootings, meets his informant to retrieve a file on American military veteran and former NATO operative Colonel Benjamin Ford (De Niro). Meanwhile, Ford has retreated to a cabin somewhere in the Appalachian Mountains of Tennessee, to try to forget the war. Now a recluse, he meets Kovač, posing as a European tourist, during a hunting trip. The two men become friendly, until Kovač reveals his true identity.
