Stephen Chow is the Handsome Tricky Master, a fellow who uses cartoonish gags to, for example, drive a man seeking a divorce crazy, so his wife can have him institutionalized. Meanwhile, Rosamund Kwan is a clerk at a big construction firm and dating Andy Lau. He doesn't know she is the daughter of the company's owner, working under a pseudonym to learn the business. However, her best friend Chingmy Yau does, and so does Waise Lee. To sabotage their romance, and to get his hands on Miss Kwan and the fortune, Lee hires Chow. Chow convinces Lau and his father, Jing Wong, that he is Wong's brother. Chow works at sabotaging Lau in the company.
It's all very funny, as Chow does a bunch of crazy stuff throughout. Miss Yau is a fit comedienne to go up against him, Wong is very funny in an evening gown, and Lau is the stalwart innocent. Full of the sort of gags that Western audiences know Chow for , his anything-for-a-gag shtick kept me smiling throughout.
