A driver’s act of debauchery almost ruins two marriages in this uproarious comedy. To protect his own identity, driver Ah Fook (Yu Ming) visits a prostitute posing as his young master Lau Chi-ping (Cheung Ying-choi), nearing ruining his marriage. Ah Fook is exposed in the end by his feisty wife Ah Fung (Helena Law Lan) and gets a well-deserved beating from her. Yu Ming is hilarious as an everyman who schemes about outside, but is slavishly obedient to his wife at home. His scene opposite Helena Law Lan is the comic high point of the film, marking the beginning of a great acting partnership.
