Chung was adopted by a Taiwanese billionaire after his parents were murdered when he was ten. He and his older brother Cha and younger sister Ching were first sent to work together in an orchard but lost touch after Chung was adopted. After awhile, Chung decided to return to Hong Kong to try to locate his siblings, but they prove difficult to find, especially since his brother Cha has joined a gang in the hopes of avenging his parents' death.
