Mild-mannered Paul Blart has always had huge dreams of becoming a State Trooper. Until then, he patrols the local mall as a security guard. With his closely cropped moustache, personal transporter and gung-ho attitude, only Blart seems to take his job seriously. All that changes when a team of thugs raids the mall and takes hostages. Untrained, unarmed and a super-size target, Blart has to become a real cop to save the day.

After a heist goes wrong, a professional team of thieves hide out at an isolated motel and try to figure out what went wrong, and their next move. Tensions rise throughout the night but they must learn to come together in order to withstand those who seek to destroy them.
