She gets her wish when the enigmatic Lucy invites her to join two other girls in a shared house for their second year. As Margot gets to grips with their new foursome, and her new life living next to a boys' Greek fraternity house, she begins realise that something's off about Lucy, she's not quite what she seems.

Between the frat parties and unauthorised nights at a bowling alley, Margot tries to find out what Lucy's hiding. But when a boy from the frat house next door disappears, the girls are forced to make decisions with deadly consequences.
