"Although Zhong Qiu (Li Cansen), a Hong Kong street gangster with a miserable family background, is confused about the future, he is very generous and loyal. He "covers" the mentally retarded boy Aaron (Li Dongquan) who is always bullied as his relative. When he was seriously injured and lying in the hospital after being stabbed by his enemy, Aaron, who was sent by the boss to transport poison, was beaten to death."
