The story starts with a teenage girl coming home brought by the police. Sophie has no memory of the previous night and has a hangover. But very soon there is news about one of her friends dead. Killed. Murdered. Making things even more strange, there are emails with photos on her phone. Photos of her friend 's body, photos of herself in the same room. Is she involved in her friends' murder?
Sophie's mother is very worried about her daughter. Karen suffers from agoraphobia and is too afraid to go outside the house. She feels that way since she was attacked by a serial rapist in her own car. Nothing is same since then.
