In Hong Kong, Chaibat welcomes Ka-Kui and Yang to his luxurious hide-out. He takes them with him to a big opium grower's fortified compound in the Golden Triangle of Thailand, for a meeting of big-time heroin traffickers. During the meeting, Chaibat's gang attack from outside while Ka-Kui and Yang protect him inside. In a huge gun battle, Chaibat's gang kill the rival traffickers and their guards, and smash up the compound. The grower survives, but will now sell only to Chaibat at Chaibat's price.
