The Line.

Being police officers has stripped Max and Donny bare, to the point where they're about as morally ambiguous as the criminals they chase. Max has developed his own methods for dealing with bad guys, having lost interest in conventional police work, while Donny has become slightly unhinged by the job yet remains faithfully optimistic. The partners' paths cross with local drug dealer Carlos, who's caught in a turf war and whom Max uses to infiltrate the neighborhood's criminal underworld.
