Three female detectives - from Hong Kong, Korea and Singapore - go undercover in a cabaret to expose a murderer.

The plot follows the titular gang of misfits, gathered together by Chen Kuan Tai (a real life martial arts champion who starred in many films for the studio) in order to protect a patriotic general from a scheming usurper. To this end, the unlikely heroes act as the general’s escorts on a dangerous journey to a distant British consulate, beset by enemies and sinister Japanese interference along the way.

An honest, diligent and helpful taxi driver Chen Kuang (David Chiang) gets involved in a bank robbery, and the police mistakes him as a robber. He together with a driver Tu Fa (Wang Chung) strives to gather evidence. After some twists and turns, the two finally are able to help the police in bringing the culprits to justice.
