In the hilarious action-packed comedy National Security Martin Lawrence (Earl Montgomery) stars as a cocky L.A. P.D. cadet who would probably be a great cop if he weren't such a show-off. Earl's rebellious attitude gets him thrown out of the police academy and he has to settle for a job as a lowly security guard with 'National Security'. After a run-in with an uptight police officer Hank Rafferty (Steve Zahn) Earl accuses him of harassment. Hank loses his badge is thrown into jail and eventually winds up working for National Security as well. Earl's overzealous behavior leads to a sophisticated smuggling operation led by Nash (Eric Roberts) and a possible police cover-up. Now everyone wants Earl and Hank dead - though they just may kill each other first!
