The eldest brother of the Chang family, Chang Man (played by Wong Pak Ming), has a successful career, but he dislikes his wife, Cheng Dasao (played by Sandra Ng), who is a yellow-faced woman and does not know how to dress up. Cheng Dasao serves her parents-in-law who are suffering from dementia at home every day, and is deeply loved by Chang Sao (played by Leslie Cheung) and Chang Huan (played by Stephen Chow). The sissy Chang Sao and his "manly" cousin Liang Wushuang (played by Teresa Mo) are a pair of sworn enemies, but when both of them are emotionally hurt at the same time, they fall in love. Chang Huan is a famous playboy, but he accidentally broke his brain, and his girlfriend He Liyu (played by Maggie Cheung) is still willing to stay with him. When everyone has someone they love, they have to help the eldest brother find a way to save his relationship with Cheng Dasao.
