"Your son is missing." It's the phone call every soldier's father dreads. Hank Deerfield (Tommy Lee Jones) had never thought that this call would come whilst his son was in the U.S., home from serving in Baghdad. Facing military indifference to the disappearance, Hank takes matters into his own hands to discover what's happened to his son and with the reluctant help of police detective Emily Sanders (Charlize Theron), Hank embarks on a journey that will bring him up against the closed ranks of the armed forces and the harsh realities of modern warfare.
