Late summer. Michel and his wife and three girls are returning from a family vacation which was more tiring than relaxing. The car has no air conditioning, the girls are cranky, and Michel has about had it. They stop at a highway rest stop. There, in the men's room, Michel meets Harry. Michel doesn't recognize him but Harry insists that they were friends in high school. Harry is now rich, with a fancy car, a young girlfriend and no kids. And, for some reason, he decides to do anything he can to make Michel's life easier. But Harry is willing to go much further than Michel could even imagine... A polished and ironic thriller based loosely on Hitchcock's Strangers on a Train.
