Noah Potter has come to Hong Kong to find his missing sister, Lianne, who disappeared after leaving him a voice mail pleading for his help. Unfortunately the Hong Kong police are unwilling to help him, so Noah has to find her himself. Noah's search for his sister brings him across Wei Tseng, leader of the Dragons, a group of dedicated men and women willing to do whatever it takes to keep their district safe from the violence and triads that plague the rest of the city's underworld. Wei is a man of violence but also one of incredible compassion, and his history is one that resonates with Noah, igniting a passion neither man expects. Together they search for Lianne, a search that will lead right into a conflict with the Dragons' greatest rivals in the city.
