Paul Blart: Mall Cop

A security guard at a mall dreams of being a cop, but keeps failing the test. So he pretends to be a policeman at work. He's generally unhappy, and his attempted relationship with a pretty worker at the mall is not going well. Then one day, some robbers try to take over the mall, and take some hostages, including the woman of his dreams. He decides to rescue her, which gets more complicated once the real cops and SWAT team start getting in the way.
