The anxiety of rush week turns into sheer terror when sisters of a sorority are slain -- and turned into dolls -- by a serial killer. New pledge Riley (Lala Kent, "Vanderpump Rules") and her best friend, Becks (Mia Frampton), must endure late-night hazing rituals as the murderer watches and waits. Can Riley uncover the terrible secret shared by her cop father (Randy Couture, The Expendables franchise) and deceased mother, a former Phi Lambda sister, before becoming a victim herself?
