What happens when a $20 million diamond gets stolen, then stashed in an unfinished building that turns out to be the new 37th Los Angeles Police Precinct two years later? Jewel thief Miles Logan (Lawrence) has to go in as an undercover cop to retrieve his loot. After a short jail term, Miles learns everything there is to know about the boys in blue in order to blend in and cash out. But the new cop soon discovers that he is a better law enforcer than he was a crook - until his old ways come back to haunt him.
