The film is about Jim, a lazy slacker who is trying to get a well-paying job but instead ends up as a night janitor for a department store. On his first shift at his new job, Jim is locked, alone, in the store by his boss. Josie, the stereotypical "spoiled rich girl" is a runaway hiding in the store after it is closed for the night. Josie and Jim identify each other as kindred spirits and proceed to enjoy the freedom of being locked together in the store overnight. But things become complicated when two incompetent crooks break into the store and hold the two teenagers hostage until the tables are turned.
