The film is adapted from Chinese classic comic series Mr Wong, with Tang Bik-wan joining hands with the magnificent Sun Ma Si-tsang and Tam Lan-hing to give a dazzling performance. Wong (Sun Ma Si-tsang) passes off as the company's manager to pursue the beauty Hui (Tang Bik-wan) behind his fearsome wife's (Tam Lan-hing) back. Unbeknown to him, Hui is actually the fiancée of his nephew (Sima Wah-lung), to whom he has refused to lend money. Scenes in which Hui plays pranks on him and tricks him into providing funds for her are spiced up by the lively acting of Sun Ma as a wife-fearing perv and Tang as a sassy girl with a sharp tongue. The film ends with Wong making excuses to meet Hui at a hotel but getting caught by his feisty wife. Whilst both are acclaimed comedians in their own right, brassy Tam and composed Tang together pull Sun Ma's leg in an unmissable classic slapstick.

Mr Wong falls head over heels for Lan, a beautiful waitress. He bugs her constantly to ask for her hand, and even goes as far as lying about his wife being dead and secretly planing to marry his wife off to a friend. Lan decides to play a prank on him to teach him a lesson.
