One of Jackie Chan's weaker efforts, this story of twins separated at birth relies too much on its premise instead of paying attention to even, coherent plot development. Chan plays two roles, one a concert pianist and the other a street guy with a knack for getting into trouble. The gimmick isn't enough to pull the story into shape, and character development is only given the cursory nods mandated by the plot. Still, Jackie Chan's screen presence and unflagging sense of humor make it all quite watchable.
