It's the anniversary of the date he lost his family and Jack doubts he'll ever find those responsible. Depression has taken hold, and he pulls out his Beretta for the last time. As he fingers the trigger, Ray shows up with the identity of the man who'd killed himself in Jack's house weeks before, leaving a note simply saying, "I'm sorry." Jack soon finds himself dragged into San Francisco's underbelly and his life threatened at the hands of the city's deadly Chinese gang, the Jade Dragons. When things become more dangerous, Jack must keep pushing forward, even knowing it could mean his death because the gang's leader, Li Zihao, may have the answers Jack's looking for-who destroyed his family and what happened to Leah. Is Jack ready for the truth?
