Master jewel thief Miles Logan (Martin Lawrence) has a big problem. A $20 million problem. Recently released from prison for the botched heist of a huge diamond, he's anxious to retrieve the hot rock which he hid at a construction site two years earlier. Unfortunately, his hiding place is now at the center of a recently completed high-security police precinct. Posing as a detective, and partnered with straight-laced rookie Carlson (Luke Wilson, Home Fries, Bottle Rocket), Miles utilizes his criminal expertise and inadvertently rises up the ranks, winning the respect of his fellow "boys in blue."
