Half-human, half-vampire Rayne is beautiful and brutal, skilled and savage. She is also a slayer with a mission: to destroy all true vampires and finally put an end to the tyranny of the undead. From Old Transylvania to the town of Deliverance in Old West USA, Rayne now faces her most bloodthirsty nemesis: Billy The Kid.

The infamous gun-slinging legend has risen from the dead and is now hell-bent on creating a kingdom of vampires to prey on the living on this cowboy frontier. With few allies and a growing army of reanimated villains closing in on her, Rayne must make her last, bloody stand in this small corner of the very, very Wild West.

Blood, broken bones and balls-to-the-wall action: this is how the West was really won!
