A martial artist busts a gang of fumbling bank robbers then has to fight angry crooks trying to retrieve their stolen loot. Twin brothers JIMMY and JOHNNY LONG are born to poor parents and separated at birth. Jimmy is adopted by a blind midwife, grows up in Hong Kong and becomes an unlucky cab driver to pay for his mother's eye surgery. Upon foiling a gang of bank robbers, Jimmy is continually harassed by angry thugs for putting a stop to their crime spree. Johnny Long is in town filming the action flick "DOUBLE STRIKE." The gang mistakes him for his taxi driving twin brother and attacks the actor to seek revenge; believing he is the one who ruined their criminal career. Jimmy moonlights as a screen double for Johnny and performs several dangerous stunts to pay for his mother's rising medical expenses. Jimmy and Johnny interact throughout the film but never meet face to face until the last scene.
