Tian Yi Bang (Li Nan Xing) was a wayward teenager who was in and out of the reformatory until he was sentenced to 18 years of jail for robbery and assault. After he was discharged from prison 15 years later, he vowed never to go back to his old ways and set out to look for the son he has never met. Yi Bang’s good friend, Mo Da, mysteriously died two days before he was released from jail. Liu Jia Li (Fann Wong) takes over Mo Da’s criminal organization and tries to rope Yi Bang in to help her.
