Ah Fang (played by Anita Mui) is the mother of two children. On this day, she was inexplicably involved in a murder case. Although her husband took her two children to run around to seek justice for her, Ah Fang was eventually sentenced to death. Later, her husband also abandoned his two sons Ah Jian (played by Felix Wong) and Ah Kang (played by Deric Wan) and committed suicide. Although Aunt Yun was just a cleaner in the hospital and did not earn much, she could not bear to see the two children alone, so she adopted them. In addition, Aunt Yun also adopted two other orphans, and the family of five lived a poor life. Ah Jian gave up his studies at the age of 16 for a living and became a taxi driver. Ah Kang was very motivated. With the support of his eldest brother, he graduated from the Law Department of the University of Hong Kong with excellent grades and successfully obtained a lawyer's license. Although Ah Kang is very capable, he is very cruel and will do anything to achieve his goals; while Ah Jian is just the opposite. He is very upright and never vague in the face of right and wrong. The two brothers are about to start a love-hate relationship!
