The TWIN DRAGONS want to borrow a boat from NING to escape FA. By chance, they learn that someone wants to ambush NING. CHAI SHIU is rich from running his family mining business. He is in alliance with the Li Clan. SHIU has loved NING for a long time. In order to please her, he holds a banquet and invites the villagers to celebrate her birthday. FA fears that if SHIU marries NING, the Li Clan will become even more powerful. Therefore, he hires the Sea Sand Clique leader YAM SIU MING, who has a bad reputation, to ambush NING. NING is hurt, but the TWIN DRAGONS save her. They explain their reason for being there to NING. They cross the river with CHEUK, NING and CHI using a ferry borrowed from CHI’s brother SUNG SZE TO. FA and the Sea Sand Clique gang pursue them. CHEUK wants to protect the TWIN DRAGONS, and so asks them to leave with CHI and NING. Suddenly, an undersea eruption sinks all the boats.
