Five friends returning from a marriage in Canada return home to the United States. Not far from the border, two customs officers stop them to check their identity. Suspicious, they take their time especially with Jalil, a man of Arab origin. The situation worsens when a customs officer finds a small bag of marijuana in the luggage. Then things degenerate rapidly: a customs officer grabs the little dog that's part of the group and slits open its belly to be sure it's not a mule. When Gab makes a move, he's shot. The customs officer orders the surviving friends to undress and put on orange coveralls. Gradually, it dawns on the four tourists that they are in the hands of former torturers from Guantanamo.
