Eric (Alex Fong Lik-Sun) and Cheun (Sammy) are two medical students who opt to rent a flat in a secluded housing estate, the reason being to concentrate on their upcoming exams. Their best intentions go south damn quick; first of all, Cheun wastes time and acts extremely annoying, thereby ruining any chance at serious study time. Second, there may be vampires in the building. Eric becomes slightly enamored of Jade (Miki Lee), a pretty young thing who lives in the building with her older sisters (Zuki Lee and Cynthia Ho). But after a series of weird noises and the appearance of a man bleeding from the neck, Eric thinks something may be up. He enlists the help of TV occult expert Mister M (Yuen Wah), who all but confirms Eric's suspicions: the sisters are vampires. Worse, they must suck the life out of one good man to cure their aversion to daylight, and have ear-marked Eric as the designated \"good man\".

As a conceited scholar of the Ming Dynasty, Wei Yangsheng believes that since life is short, one should pursue the ultimate sexual pleasure as time allows. Wei Yangsheng encounters Tie Fei the Taoist priest's daughter, Tie Yuxiang, on an occasion. With the former's talent and the latter's beauty, they fall in love at first sight, and Wei Yangsheng is later married into the Tie's family. Yuxiang is elegant and courteous under the influence of her father's faith, though her lack of passion cannot fully satisfy Wei Yangsheng's sexual needs. His disappointment is no less than his affection for her. Written by Mark Wu
