A string of brutal murders has bodies piling up in Brooklyn, and Detective Frankie Donovan knows what is going on. Clues left at the crime scenes point to someone from the old neighborhood, and that isn't good.

Frankie has taken two oaths in his life—the one he took to uphold the law when he became a cop, and the one he took with his two best friends when they were eight years old and inseparable.

Those relationships have forced Frankie to make many tough decisions, but now he faces the toughest one of his life; he has five murders to solve and one of those two friends is responsible. If Frankie lets him go, he breaks the oath he took as a cop and risks losing his job. But if he tries to bring him in, he breaks the oath he kept for twenty-five years—and risks losing his life.

In the neighborhood where Frankie Donovan grew up, you never broke an oath.
