Troubled Cody (CORY KNAUF), a second-generation member of a violent and notorious Northern California biker gang, rides out with his friends to a party at a farmhouse located deep within the redwood forest. At the end of the wild evening, things take a turn for the worse when Cody's ex-girlfriend Michelle (TIFFANY SHEPIS) is discovered wandering aimlessly and covered in blood, screaming and convulsing as if she were possessed by something unworldly. Cody and the others desperately try to get help for Michelle while stuck in the middle of nowhere, but their plans are quickly ruined when another malicious gang, seemingly from the 1950s, shows up looking for a few kicks. However, this ominous Rockabilly gang is not there to pick a fight. They want what's mysteriously growing inside of Michelle -- something very evil and powerful -- and they will stop at nothing to get it!
