Across the River (2008)

In the wake of a major battle of Iran-Iraq war, a cameraman finds himself stranded in the wilderness alongside the only other survivors, an Iraqi and an Iranian soldiers. With a single gun between them, the soldiers alternatively take each other hostage, marching aimlessly upon the scorched earth to an unknown destination. Realizing that neither has anything left to go back to, they form an unlikely friendship, to which the cameraman is the sole witness.
