A marine, who has a wife and two little girls, leaves to afghanistan. They crash and the marines thinks there is no survivors. So his family has a funeral, etc. Over the months following, while he is being held by Afghani's, his wife starts falling in love with his brother, and at one point they kiss. Eventually, he is found by the Americans, but comes home to find that his brother has in away, started talking his place.
It's really sad but amazingly done and completely and totally original. I really loved it, and it isn't what you expect at all. :thumbup
