In the dead of night, Paul Conroy, an American truck driver employed in Iraq in 2006, slowly comes to terms with the fact that he is buried alive and imprisoned within a wooden coffin. He can see the trap he's in with his cigarette lighter, and he immediately understands that there isn't enough air for him to survive for very long. He discovers a functional cellphone within the coffin, enabling him to communicate with the outside world. Finding a man buried in a box in the middle of the Iraqi desert, however, turns out to be difficult without assistance from the outside world. The best resource Paul has to rely on is himself.
