On the run from the mob, a trio of 1920's Chicago Jazz musicians take a job from an elderly reverend, playing for what they think is his wife's funeral in the backwoods of Illinois. Unfortunately, the funeral is actually an elaborate cult ritual to raise the spirit of an evil sorcerer who swiftly begins raising the dead and terrorizing the innocent townsfolk. With monsters, moonshiners and mobsters on their trail, the friends must draw upon their various talents to stop this evil, save the townspeople and escape with their lives.
