Hell's Bounty

A bounty hunter named Smith is in the no-account town of Falling Rock to collect on a renegade. He miscalculates the length of fuse needed on a stick of dynamite and finds himself in the anteroom of hell. It's a bad place, but not as bad as what he senses through the next door. He accepts a job to return to the living world and combat the rise of an evil feared by the devil himself. His team consists of the most popular whore in town, an Indian chief, a young gunfighter, and the alcoholic town doc. (I think some of these people, like Smith are already dead.)

This mash up of Wild West action, Lovecraftian horror, and low comedy works better than it has any right to.
