Although Gan Lianghong (played by Nick Cheung) is the only son of Gan Shupei (played by Paul Chun), the leader of the aviation industry, he is cheerful and approachable, and has no airs. He met Xiong (played by Chan Kam Hung) by chance and became friends. Compared with Hong, Xiong's family background is much more ordinary, but he has a happy family, with his loving mother Mei (played by Xue Ni), his elder sister Ming (played by Guo Aiming) who is thrifty and waiting to get married, and his smart and beautiful second sister Hui (played by Zhou Haimei) who is a stewardess. The family is happy. Wen (played by Luo Jialiang), who is addicted to gambling, is a grudge against Ming. Ming lost her savings for many years and was abandoned by her fiancé. However, fate has already taken a turn. Ming entered the company of Gan Shupei's younger brother Sheng (played by Huang Rihua) as a secretary, and they became husband and wife because of fate. Unexpectedly, his younger sister Hui has always had a crush on Sheng, and even had sex with him when drunk. However, in order to protect her sister's marriage, Hui chose to escape. Xiong falls in love with stewardess Sun Hua (Ada Choi), but Sun Hua is vain and Xiong's family background cannot satisfy her. Sun Hua and Hong are in love. However, a bigger turn of fate occurs. It turns out that Xiong is Gan Shupei's biological son. Mei secretly swapped the two babies as revenge. The revelation of this fact turns the lives of these young children upside down. The grievances and evil obstacles of the previous generation are grafted onto the next generation and continue.
