Paul Blart (Kevin James) is a hard worker, but has never landed his dream job of being New Jersey state trooper due to his excess weight. Determined to support his mother and his daughter, Blart takes the slightly less glamorous post as the security guard at his local shopping mall. He never complains, approaching the job with impressive diligence and pride, but doesn't get much respect for it. It's only when a group of misfits in Santa's Helper disguises take hold of the mall and several hostages, that Blart's would-be cop smarts come in handy and he gets a chance to shine. With a deadly situation on hand, Blart may finally be able to show the world (and his romantic interest, who just happens to be one of the hostages) what he's made of. Though the villains have several advantages over him, Blart has a Segway scooter and a big heart on his side.
