Ben Lam Kwok-Bun plays Ching Fung, a Western-style vampire who just wants some booty. His quarry is Rainbow (Yvonne Yung Hung), a blind prostitute who only works to save up for an operation to restore her sight, and who doesn't realize that he new boyfriend has fangs or drinks blood. He actually doesn't want to partake of her because she resembles his old girlfriend, who died many years ago, so he tortures himself by abstaining in an attempt to prove his love to her. Meanwhile, his fellow vampire (Mondi Yau Yuet Ching) seems unhappy with his new dietary habits.
