HARPER WONG (LO KA LEUNG, GALLEN) was born and grew up at a market. He manages his adopted father, CHAI’s vegetable store. His neighbours, YING (LUI SHAN) and LAI (LIEW HIU TUNG) treat him like a god while his good friends, KUEN (TSANG WAI MING) and KEUNG (CHAN KWOK PONG) take him as their leader. HARPER finds some hawkers selling contaminated vegetables and threatens to report them. He scares them away from the market. His brother, SCOTT (LI KA SING, DICKSON), crashes his car into YUMMI’s (NG WING MEI). She demands compensation. HARPER arrives on the scene and settles the argument with some money. HARPER’s wife, CHU (NG MEI HENG, MELISSA), is dominant. She scares everyone off, but HARPER treats her like a queen. CHAI has bet on the same Mark Six combination for 17 years. He finally wins the first prize which gives him $20 million. YUMMI and her mother GI meet HARPER while they are moving house.… ...

YUMMI threatens to call the police because CHAI and some others have gathered outside her flat. HARPER asks them to leave first. Seventeen years ago, CHAI used to share Mark Six tickets with YUMMI’s father, SHUI. They won it once, but SHUI took all the money and disappeared. CHAI’s daughter, KI (NG MAN YAN, NATALIE) and SCOTT follow YUMMI hoping that they can get the valid ticket back. CHU’s mother, HUNG (PAK YAN) does not like HARPER very much because of his poor family background. CHU tries to flatter HARPER for her own face. CHAI and KEUNG break into YUMMI’s home to look for the ticket. Meanwhile, YUMMI comes back home. They flee from a window and drop into a dumpster. She calls the police. They are all arguing in the police station and blaming each other. YUMMI decides to sue CHAI and KEUNG. CHU and HUNG are annoyed when they are called to the station. CHAI loses control and throws his shoe at YUMMI.… ...

HUNG criticizes CHU for getting pregnant and marrying HARPER. She then blames HARPER, but he cannot talk back. YUMMI finds CHAI’s Mark Six ticket and plans to take all the money. HARPER begs her to settle the case charging against CHAI and KEUNG, but she refuses. CHAI finds GI has blacked out at home and sends her to the hospital. However, YUMMI is not impressed. GI asks her to let go of the ticket because SHUI abandoned them once he had money. She worries that bad money will bring nightmares to them again. In court, YUMMI gives vague testimony, so CHAI and KEUNG are freed. She worries that her boyfriend KEI (TANG HO KWONG) has met an air accident. She fears GI’s warning will come true and wants to share the money with HARPER. He agrees, but the ticket has gone missing.

HARPER, CHU and YUMMI cannot find the ticket. Everyone is disappointed. YUMMI claims HARPER owes her $10 million. HUNG hurries CHU to apply for emigration to Canada. HARPER does not want to leave his family, but CHAI supports the idea. He finally agrees to do so. CHU signs him up for a series of courses in preparation for their life in Canada. Everyone is happy about his bright future. SHUI tries to divorce GI, but she refuses. YUMMI runs to the market and SHUI follows. CHAI sees him and starts bombarding him about his bad acts. With some neighbours’ help, they chase him away. KEI proposes to YUMMI on his return to Hong Kong.

YUMMI is busy organizing her wedding. Her best friend, RAY (TAI CHI WAI) helps her. She dislikes KEI’s secretary. After transferring her, she brings CHU into KEI’s company. GI sets up a flower shop in the market with CHAI and the others’ help. CHU is impressed with KEI’s look and talent. She feels that HARPER is an embarrassment in front of her colleagues, so she signs him up for more courses and leaves him no time to have lunch with her. CHAI does not want to bother HARPER studying, so he takes care of the store alone but makes a big mess. The market management company proposes a huge rent increase. HARPER represents the tenants for negotiation and misses his appointment at the Canadian consulate. During the negotiation, the management company representative thinks that SCOTT has threatened him with a bottle of thinner, so HARPER and the others are arrested.
