The 17-year-old homeless girl Franzi, who goes by Fox, suddenly disappears, to the alarm of her friend, known as Hedgehog. Fox is diabetic and doesn’t have any insulin with her. She recently had an argument with a friend, a drug addict who had stolen money from a dealer. Fox also suddenly needed a lot of money – and offered her teacher Mr. Grove sex in exchange. Did he take her up on it and then make her disappear afterwards?
