The target of the mission is a drug lord named Chaibat. In order to infiltrate Chaibat's Triad organization, the plan is to get close to Chaibat's henchman Panther, who is being held in a Chinese prison labor camp in Canton. Ka-Kui, posing as a petty criminal, is able to help Panther escape with the aid of Chinese military police, who eliminate Panther's men in the prison. Panther then meets up with some of his other men, and Ka-Kui helps them escape to Hong Kong.En route to Hong Kong, Ka-Kui, along with Panther and his men pass through the supposed home-village of Ka-Kui's undercover role. Panther insists that Ka-Kui visit his family there. Realizing he does not actually know anyone in the village, Ka-Kui is apprehensive but is pleasantly relieved to be greeted by undercover military police posing as his family, with Yang posing as his sister. Yang and the Chinese military police help them win Panther's trust by faking the murder of a policeman by Yang.After arriving in Hong Kong, Ka-Kui, Yang and Panther go to Chaibat's luxurious hide out.

However, Chaibat needs to keep her alive because she knows the secret codes to his Swiss bank account, and she will not reveal them to anyone but her husband.More difficulties arise when Ka-Kui happens to run into his girlfriend May at a Malaysian resort hotel. She confronts Ka-Kui, and the situation turns into a misunderstanding, with Panther believing that Ka-Kui was trying to proposition a prostitute.
