He receives a visit from his rich mother-in-law (Yan Pak), who is convinced that her daughter, Ah Kuen (Sylvia Chang), has married a good-for-nothing man.
Hui faces competition when a profit-oriented businessman, Danny Poon (Lawrence Ng), opens what is to be the first of a fast food chain of fried chicken restaurants across the street from him.
Danny's Chicken employs a wide range of marketing techniques that makes them instantly popular, causing Hui's business to plummet.
He finds out that his son visited Danny's Chicken with his girlfriend Judy (Gloria Yip), and decides to infiltrate the rival business dressed as an Indian woman, but is quickly exposed by Poon.
Hui tries to turn his luck around by adopting Poon's marketing techniques and "packaging" in order to appeal to the fashionable crowd, redecorating and holding a disastrous karaoke night.
Angered that his fast food chain has been defeated, Poon resorts to an arson attempt that goes wrong and ends up setting Danny's Chicken on fire before he is rescued by Hui.
