The drug trafficker who refused to collaborate with FOON-HEI is being killed in the detention house. FOON-HEI gains full control of Hong Kong's drug market successfully. FOON-HEI appreciates KA-KEUNG and he asks him to handle the drug trafficking business for him. SIN-YAN accidentally discovers the eavesdropping device from CHEUK HOI. On the other hand, CHEUK HOI invites SIU-KA to meet up for information exchange. In order to get rid of SIN-YAN, CHEUK HOI runs away with SIU-KA by car. SIU-KA learns that CHEUK HOI is being investigated by the ICAC. Together with HO-KAN, they try to find out if CHEUK HOI is trustworthy. FOON-HEI asks KA-KEUNG to meet up with the overseas drug trafficker in the hotel. SIU-KA accompanies KA-KEUNG to the hotel and the drug trafficker asks SIU-KA to taste the drugs. In order to protect SIU-KA, KA-KEUNG tastes the drugs instead. The transaction is successful but KA-KEUNG is dying.
