The legend of a demon named Trick (Malcolm McDowell) trapped in a Jack-o-lantern inspires a rhyme. “Peter, Peter, pumpkin eater had a wife and couldn’t keep her. So, he put her in a pumpkin shell, and there he kept her very well.” The trick is figuring out how many pieces you have to cut your wife into before she’ll fit inside a pumpkin. Pastor Joseph (Gary Busey), believing the legend, tracks the pumpkin to a biker bar where it is being used as a tip jar. He tries to warn the bartender but is dismissed as crazy. On Halloween, Ashley and her costumed friends stumble upon the bar. When one of them is accidentally killed, the others find themselves threatened with torture and death by the bikers. All seems lost, then Ashley hears Trick’s voice in her head, teaching her how to trick the gang. But is this ancient pumpkin trying to help her? Is he just making things worse? Or is he merely the product of Ashley’s panicked imagination? The trick is figuring it all out before everybody dies.
