Four New York city cops are dead, killed in an ambush that has the entire police department on alert and on edge. With a cop killer on the loose and so much riding on the case, Chief of Manhattan detectives Francis Tierney, Sr. (Jon Voight) asks his son, Detective Ray Tierney (Edward Norton) to lead the investigation. Reluctantly, Ray takes over the case, knowing that the cops who were lost, had served under his brother, Francis Tierney, Jr. (Noah Emmerich) and along side his brother-in-law, Jimmy Egan, (Colin Farrell).
On the surface it looks like a routine drug bust gone terribly, tragically wrong, but as Ray delves deeper into the case, he realises that someone had to have tipped off the drug dealers that the cops were coming. Someone on the inside. Worse, the evidence starts to point in an unthinkable direction: to his own brother and brother-in-law.
As the questions mount, the case forces the family to choose between their loyalties to one another and their loyalties to the department
