Mary Lou, the prom queen burned to death by her boyfriend back in the fifties, has escaped from hell and is once again walking the hallways of Hamilton High School, looking for blood.

Michael is a young boy living in a typical 1950s suburbanite home... except for his bizarre and horrific nightmares, and continued unease around his parents. Young Michael begins to suspect his parents are cooking more than just hamburgers on the grill outside, but has trouble explaining his fears to his new-found friend Sheila, or the school's social worker.
