Synopsis

Separated during a chaotic hospital escape, identical twins grow up in entirely different worlds. John Ma becomes a refined pianist and conductor in New York, while his brother Boomer becomes a tough mechanic, street racer, and martial artist in Hong Kong. When John returns for a concert, mistaken identities draw both brothers into criminal trouble, romance, and a string of comic action set pieces.
