Narc

An undercover cop named Michael Calvess has been killed in Detroit, and eighteen months on, no one has said who did it. Nick Tellis (Jason Patric), a narcotics detective on leave after a bad night on the job, is called back to work the case beside Henry Oak (Ray Liotta), the dead man's ex-partner. Joe Carnahan puts the two of them in the city's back alleys, and Tellis, who needs this case more than he admits, starts taking Oak's methods as his own.
