Director Gavin O'Connor collaborates with Narc director/screenwriter Joe Carnahan on this family-focused police drama concerning an honest homicide detective (Edward Norton) assigned to investigate the precinct run by his potentially crooked older brother (Noah Emmerich). As the investigation begins to reveal some troubling facts about the precinct, it gradually becomes apparent that the policeman who is also the older brother's best friend (Colin Farrell) may be the man orchestrating many of the suspected crimes.
