The Mermaid

Playboy business tycoon Liu Xuan purchases the Green Gulf, a wildlife reserve, for a sea reclamation project, and uses sonar technology to get rid of the sea life in the area. Unknown to him, the Green Gulf is the home of merpeople, and the sonar has caused many of them to die or get sick. The few survivors live in an abandoned shipwreck in the gulf, and want to assassinate Xuan for his deeds. The merfolk send Shan, a beautiful mermaid who's trained to walk on her fins and hide among humans, in a "honeytrap" plot against Xuan. On the night of Xuan's party celebrating his success, Shan, pretending to be a dancer, gives her telephone number to Xuan.
