Gallen Lo
Lee Kei (Gallen Lo) is a righteous cop who refuses to follow the majority of most Hong Kong police officers who accepted bribes during the 1960s. Wanting to move away from his supervisor who is a corrupted cop, Kei reports it to his precinct Lieutenant, who is unable to do anything about it since his superior is also corrupted. In order to protect Kei, he has him go undercover to find the infamous cat burglar "Black Rose", who has escaped being captured for over twenty years.
