It is about John Sutter, a Wall Street lawyer, and Frank Bellarosa, a mafia don, and the conflict between the two that occurs when Bellarosa moves to the North Shore, the same New York neighborhood as Sutter. Bellarosa befriends Sutter and his wife Susan, and convinces Sutter to represent him in a high-profile case.
