Kwong Wan Transport Co. is one of the oldest shipping companies in Guangzhou. It is managed by MAU’s son, HIN. He works for years to keep the company in good business. HIN’s only son, CHI, is a spoiled young man. He is kindhearted but he likes to play and spend. HING used to be HIN’s servant maid. She is smart and hardworking, so MAU teaches her to be HIN’s assistant. HIN’s wife, YUNG, hates HING and thinks that HIN is having an affair with her. HEI’s family collects and cleans up manure for living. Although she comes from a poor family, she is an optimistic person. She is upright, too, always takes up the cudgels for the weak. CHI always comes home late and uses HEI’s manure buckets to climb up the wall. He often knocks over the buckets and she has to clean up later, so HEI dislikes him. On MAU’s birthday, YUNG’s brother, SAM’s son, dies from a drowning accident……

SUM loses his mind after his son dies. HIN orders his uncles, TUNG and CHEONG, his cousin, FAI and his sister, FUNG to control SUM. YUNG wants to hand in KUK to SUM. HING fails to stop her, so she hides KUK. SUM eventually finds KUK. CHEONG and FAI gloat, while SUM flies into a fury. SUM wants to kill KUK. HIN protects her against SUM. From then on, SUM always finds chances to have his revenge. CHI, HIM and, YEE are famous bullies in school. They bully HEI’s good friend, LAI. HEI cannot stand them and complains to the principal, MARTIN. HEI, nevertheless, is made a fool by the three for this. CHEONG is aggrieved when HIN lectures him in the company. He therefore sows discord among the staff. CHI comes home late again. HIN learns his bad acts from HEI and decides to restrain him more.

HIN punishes CHI. However, MAU defenses him and makes HIN really angry. TUNG and CHEONG pay no attention. Only HING tries to help settling them down. One of the ships is missing. HIN knows it has something to do with SUM. CHI means to get even with HEI. He spends money and labor to stop HEI from working, which makes HEI very embarrassed. MAU worries about HIN’s health and asks him to stop working until he feels better. YUNG stops HING from telling HIN important news of the company. HIN scolds HING when the company loses a big business deal. HING swallows the humiliation. HIN loses his temper over the missing ship. CHEONG stirs up people to leave the company. HIN is stressed and wants to give up. Luckily, HING supports him all the time.

HIN picks himself up again after HING encourages him. He also has more control over his temper; HING is glad. CHI recommends HEI to go to school to MARTIN. She loves to study and without realizing that is CHI’s plot. HIN is burning with anger when he finds out that the Customs have detained one of the ships. Apparently, CHEONG has hidden smuggled goods in the ship. SUM learns that HIN has spent a good deal of money to try to settle the detained ship event, so he decides to ask HIN to pay back his loan. HIN is expecting this and is prepared. CHEONG dislikes HIN and asks to sell his share of the company, but HIN refuses. HEI meets her dream lover, TONG, when she is buying some books. HEI is nervous. On her very first day in school, CHI and the others welcome her on the way. HEI feels something bad is about to happen. CHI tries hard to humiliate her in front of other colleagues. HEI is not scared of him and swears to fight against him.

HEI lives in her own dream and waits for TONG to pass by every day. SUM forces HIN to pay his loan back. YUNG does nothing to help. Only HING tries hard to gather money for HIN. Although CHI bullies her all the time, HEI determines to go to school every day. YUNG demands MAU to kick HING out of the family before she asks SUM to quit forcing HIN to pay his loan. MAU is in a dilemma. HING promises to leave when HIN settles the whole event. HEI is thrilled to bits when she finally meets TONG. CHI plays a practical joke on TONG to make HEI think that TONG has a traffic accident. She is heartbroken. CHI exposes her secret to TONG. She is embarrassed to see TONG now. HIN manages to work hard with all staff to gather enough money for SUM. When they are celebrating, YUNG is furious.
