A gym-obsessed serial killer murders and eats a local drug dealer for their protein, inadvertently sparking a brutal and bloodthirsty tit-for-tat turf war between rival drug gangs.
Set in 1895, the film follows friends Ed and Frank who become brutal enemies in Oklahoma frontier territory when a rivalry develops over a woman who is set to inherit a prominent saloon. After a bounty hunter makes Ed disappear to a tortuous prison run by a sinister warden, he must learn the ways of an outlaw from a prison-mate to escape and exact his revenge.
