Lawrence plays Miles Logan, a bank robber who, after a fumbled robbery, is forced to hide his huge diamond in a building that's under construction. Imagine his dismay when he gets out of prison a couple of years later and finds out that building became a police department and his diamond is somewhere in the AC vents above the robbery division.
So what's a newly released bank robber to do? Well, impersonate a cop, walk right in and find that diamond, of course. And that's exactly what Logan does. Unfortunately, soon after getting behind the security doors as a new transfer, his superb recommendations (a bit too superb as far as Logan is concerned) net him a partnership with the newly promoted Detective Carlson (Luke Wilson) in order to help show him the ropes.
This naturally puts a kink in Logan's plan since they immediately hit the streets on a case. But thanks to Logan's inside knowledge of how criminals think and work, he solves the crime in record time. Of course, this causes even more attention to be drawn towards him and he is quickly promoted to Lead Detective. As much as Logan tries, he just can't get any alone time to find his diamond, and when he runs into a couple of old partners (one of which is played by Dave Chappelle), the matter just gets more confusing.
Before the movie is over, he will have the local detectives thinking he is FBI, the Feds seeing him as another rogue cop and the criminals not sure what is going on. In fact, in another case involving a truck full of drugs, Logan has to wear a wire and convince a bunch of crooks that he isn't a cop, while making sure the cops listening in continue to think that he is. Needless to say, Logan has to do some constant quick thinking in order to get his diamond and not have it fall back into the hands of the partner that tried to take it from him in the first place (not Chappelle's character, but one played by Peter Greene).
Special features aren't all that abundant. They consist of the HBO First Look, a making-of and three music videos. So while I really enjoyed this film, there doesn't seem to be quite enough incentive to purchase the Blu-ray version over the normal DVD release.
