Sarah returns to her old house to collect the last of her things after leaving her husband. When she goes upstairs she finds Natalie, her husbands new girlfriend there and realises that she has moved in. Slowly, the girls realise they know each other from school. Sarah remembers that Natalie had a bad reputation with the men and threatens to tell her new boyfriend what she was like back then unless Natalie rests with her. All goes according to plan and the girls have complete encasement fun, until they hear the key in the door.
