Pao Lung-Sing, a descendant of the famous Judge Pao Ching Tient, is a 9th degree corrupt judge (lowest degree) who changes his tune when he tries to champion a woman Chi Siu-Lin, who was framed for killing her husband. As a result, Pao is forced to flee and through a series of events (often hilarious) becomes a 1st degree judge and comes back to wreak havoc and justice on the guilty.

A corrupt businessman commits a murder and the only witness is the girlfriend of another businessman with close connections to the Chinese government, so a bodyguard from Beijing is dispatched to help two Hong Kong cops protect the witness.
