Carter (Thomas Jane), a troubled veteran who gets a chance at redemption by protecting a 12 year-old girl from an assassin after she witnesses a murder. Holding a shotgun with a single shell, he engages in physical and psychological warfare in a desperate fight for the girl's life. 爱情虽是一种无形的，微妙的感觉，在物质上，它没有一个可以描摹的参照实体。但是，它却是最需要空间去包容，去努力地经营的。其怪诞在于此，其神奇亦在于此。
