Three men are murdered in the city of New York - first there is the execution of Italian, old-style mobster, Ed Catalano. Then Chinese tong members are killed in the heart of Chinatown.
District attorney Butch Karp is given the cases to investigate and slowly connections between the two executions begin to appear. Everything seems to revolve around a mysterious Chinese man, known only as Leung, a shadowy figure in Chinatown that no one can identify. As Karp gets closer to discovering the identity of Leung, the lives of his family are threatened by this unseen, controlling force. Karp is determined to solve the murders, regardless of the danger, until he learns that there is an eyewitness to the Chinatown killings, his twelve-year-old daughter.
Karp's wife, infamous security consultant Marlene Ciampi, is hired by Vivian to investigate a death of her own. Hiding from her abusive husband in a shelter, Vivian wants to discover if her father's fatal leap from the EMpire State Building was suicide, or murder. Decades old, Marlene's case isn't easy; people don't seem to want to talk about Jumping Jerry's death. And someone is determined that she will not unravel the truth, someone who is willing to silence her, permanently.
As Marlene's and Karp's cases intersect and they begin to fit the disparate pieces of the mysteries together, the threat to themselves and their family escalates. They don't know where the source of the danger lies but they must discover it quickly before one of them, or their children, is killed.
