After his heroic tactics in the first film, Paul Blart is prepared to show his colleagues, once again, just what a great security guard he really can be! Blart and his young daughter head over to Las Vegas in order to attend the national Security Guard Expo. Just like back home, Blart is once again mocked by those there as not being capable of handling any real security issues. Blart must now prove to everyone in Las Vegas that not only is he capable of being a great security guard, but that he is also capable of stopping the notorious art thieves in Las Vegas.
