SING is clever and thus he finds where the secret cell is in the factory. YIP SAM's subordinates are arrested but he manages to escape.

Although FAI wants to accuse SAM, he has no evidence. They are confused.

SAM tries to have solicitors to make defense for him. He recalls KIT who has become recently. KIT is convinced.

KIT knows that KWAN is in charge of the case and SING will be a witness. He convinces them that he takes the job not on a voluntary base.

KIT manages to shirk all the accusation as he knows KWAN and SING well. They are discontent as SAM is set free at last.

MAN forces SING to migrate overseas with her. SING wants to stay and he behaves bad in the interview and his application is turned down.
