Money-minded lawyer Sung Sai Kit (Cheung Tat Ming) was extremely clever and his eloquent speech has won him thousands of cases in court. However, he had a bad reputation since he worked for whoever paid him well. Then his wife Ling Lung (Amy Kwok) got pregnant. Kit wanted to do good in his son’s name and started to be more charitable. He spared others in court and even represented orphan Sing (Fan Siu Wong) in a case. Sing’s father was misjudged as a murderer and Kit successfully proved him innocent. Not long afterwards, Ling Lung gave birth to a boy and Kit decided to retire. However, it wasn’t long when Kit was forced to go back into business.

Justice Sung II is the sequel in 1999.
