Paul Blart is a mild-mannered, dutiful family father who works as a security guard in a New Jersey mall. For years, he has applied to become a cop, but he always fails the physics exam due to his overweight. One day, a gang of organized criminals place the mall under siege and take hostages. Blart becomes trapped inside, and because of his sense of duty, refuses to leave. He thus becomes the police's eyes on the inside and has to stop the criminals on his own.
