Gavin O'Connor directs this gritty crime thriller, set on the mean streets of New York.

Ray Tierney (Edward Norton) and his brother Francis Jr (Noah Emmerich) hark from a long line of cops, following in the footsteps of their father (Jon Voight), the city's former chief of police.

When four boys in blue are killed, Ray investigates and he comes to the shocking conclusion that the culprits must have been cops.

The trail of evidence leads to Ray's conniving brother-in-law Jimmy (Colin Farrell), who is stirring up trouble between rival drug dealers and allowing the criminals to eliminate the competition.

Unfortunately for the Tierneys, a witness escapes the melee and threatens to expose the whole sordid affair, plunging the NYPD into the midst of a scandal.
