Ma (Tong Chung-yip) works as a taxi driver, as a collector for his father whose business is high-interest loans, and in his spare time, as a lifeguard. In that last role, he meets Kathy (Pat Ha), a wealthy woman, and romance blossoms. Meanwhile, Kathy's friend Louis (Leslie Chung) is also at the beach a lot and he meets a woman with the unlikely name of Tomato (Cecilia), and they develop a relationship. The two couples have various sexual encounters, and then some dastardly assassins from Japan arrive to snuff out Kathy because she has spurned the son of a major gangster. The sex and the violence are intended to make Hong Kong's beaches all that hotter, but the final judgment will have to rest with the viewers.
