Narc (2002)

An undercover narc dies, the investigation stalls, so the Detroit P.D. brings back Nick Tellis, fired 18-months ago when a stray bullet hits a pregnant woman. Tellis teams with Henry Oak, a friend of the dead narc and an aggressive cop constantly under the scrutiny of internal affairs. They follow leads and informants turn up dead.
