WA is a 17-year-old juvenile delinquent. He was imprisoned as he had committed criminal trashing. Being counselled for a period of time, WA runs a new life. However he is still being humiliated by his colleagues. He is even framed as a sex maniac on a bus by three passengers. He begs Inspector MAN to let him go. However MAN insists on formalising the procedure of accusation. At last he is condemned to imprisonment. There he is beaten up by some bad guys so seriously that he dies. YAN blames himself as he cannot give a helping hand in the case to avoid the tragedy.

On the other hand YAN's good friend WAI returns and WAI wants to be a teacher. However WAI is killed by a juvenile delinquent FAI. WAI is hurt and bleeds seriously by FAI, who wants to steal WAI's car but in vain.
