Cheung framed Chan For. Chan orders his wife not to tell this to their children, Ah Lan and Hung. His wife passes away. On her deathbed, she asked a neighbour, To Chung-man, to take care of her children. Claiming to be a good friend of their father, Chan For moves in to the bed next to Ah Lan to take care of his children. Hung likes this uncle because he always treats him generously. But Ah Lan finds "Uncle For" weird and enthusiastic. Ah Lan is forced to pay her mother's debt. Hung is suffering from acute appendicitis. To solve Ah Lan's financial problem, Chung-man returns to his rich family and accept an arranged marriage. Ah Lan decides to sell herself to the construction site foreman for one night. Chan For wants to stop his daughter from making this deal, so he agrees to work for Cheung again. The next day he carries out a robbery and is caught. Ah Lan and Chung-man visit him in jail, and hold their wedding ceremony in front of him. He looks forward to the days when he returns.
