The agents investigate the disappearance of Claire Hunter, a prep school teacher who was last seen at her gym the previous evening. She'd had a confrontation with a man at the gym who claims to have seen her subsequently getting into a car. Claire was well respected at her school and always went the extra mile as far as the students went. She had just broken up with her boyfriend Pete a fireman but that proves to be a dead end. When one of her 15 year-old students runs off with her, they can't help but wonder is they're having a relationship. It proves to be far more complicated than that with Claire having to come to terms with the parental abuse she suffered as a child and which her student now faces.
