Winchester Smith is a crack shot. Problem is, his talent is going to waste, knocking down ducks in a shooting gallery. Win wants some real action, and like Gary Cooper as Sergeant York, he's going to war, joining the U.S. Marines to fight in Central America. But serving as a messenger, he has little chance to put his rifle to use. When he does, he ends up facing a disciplinary hearing for disobeying orders. In order to redeem himself, Win will have to deliver a message that the Marines will never forget.
