KI brings WING and FAI to Thailand where there will be a drug transaction. In order to test FAI's loyalty, KI sends henchmen to impersonate policemen and take drugs from FAT. FAI tries his best to protect the drugs. He wins KI's trust. CHOI has to leave Hong Kong secretly. WA and TUNG go to arrest him. TUNG catches him so as to testify that KUEN is innocent. FAI takes a taxi-dancer to a motel as instructed by KT. He does so as he does not want KI to suspect him. However he meets YI at the motel entrance. YI is in despair. FAI gives YI a recording tape which states the reason of his behaviour. However YI does not listen to it.
