Something evil is happening at Alma High School -- an evil so unthinkable that nothing in Brett Higgins' criminal past could ever prepare her for it. When a concerned teacher suspects that a drug ring is operating at her school, Brett Higgins and her lover Allie enroll at Alma High School disguised as a teenaged brother and sister. Against her better judgment, Brett soon finds herself returning the affection of luscious cheerleader, Kathy, while Allie is stuck fighting off the raging hormones of their number one suspect, Kathy's boyfriend Brian. Then one of their classmates turns up dead, propelling Brett on a nightmarish quest to stop the terror. And putting Allie and Kathy directly into the hands of a relentless predator.
