在这部神枪救世主西部片中,The Old West comes to life in this tale of a drifter, named Lane McCrae, whose life is torn asunder when an outlaw murders his family. With his dying words he makes a pact with the Devil. Now five years later and only months after the conclusion of the Civil War, Lane renews his search for the outlaw Dillon. However, Dillon is not Lane's only prey as his deal with the Devil has him hunting rogue Demons and Angels alike. When his ex-lover, Elizabeth, resurfaces, all hell breaks loose.
When Lane McCrae confronts the outlaw that murdered his family, the battle leaves him fatally wounded. He is visited by the Devil, who offers him a deal that would save the lives of both he and his brother, but instead makes him a bounty hunter for Hell replacing his predecessor. When Zathera, the embodiment of death, walks the earth, it's up to Lane, Hawk and their team, to stop her before she wipes out humanity. They are not the only ones hunting Zathera though - there are others who want to reach Zathera first, for plans of their own!
