Miles Logan is a talented jewel thief who is involved in a $20 million jewelry heist that goes bad, and he is forced to hide the precious diamonds at a construction site. Three years later, Logan is out of jail and returns to pick up his loot. One problem: the site where he hid the diamonds is now an L.A. police precinct. To recover his stash, Logan impersonates a detective and with his rookie partner in tow, finds himself in the midst of drug busts, car chases and robberies. Using his criminal expertise to solve case after case, Logan inadvertently wins the admiration of his "fellow cops" as he tries desperately to recover his stolen diamonds.
