Six years after the heroic Black Friday rescue at New Jersey's West Orange Pavilion Mall in Paul Blart: Mall Cop (2009), Paul Blart finds himself in dazzling Las Vegas with his daughter, Maya, to attend the Security Officers Trade Association convention.
However, instead of resting and having fun, the overprotective father unearths a well-planned conspiracy, as the suave art collector and steely criminal, Vincent Sofel, and his skilled gang of robbers intend to steal a rare art collection.
Now, it's up to the selfless protector, Paul, and his equally experienced team of security guards to save the day. Will the Mall cop carry through the most difficult mission in his entire career?
