Rachel (Mila Kunis) is a criminology student hoping to land a position as a teacher's assistant for professor Robert Starkman (William Shatner). She's sure this position will pave the way to an FBI career, and she's willing to do anything to obtain it -- including killing her classmates. The school psychiatrist, Dr. Daniels (Geraint Wyn Davies), becomes aware that Rachel is insane, but Rachel is skilled at her dangerous game of death and identity theft.
