Meanwhile, a dangerous gang leader named Crazy Bull (Kirk Wong) is being transported as a captive in the same hospital. Crazy Bull escapes and attempts to take one of the twins hostage. In the ensuing chaos, the twins are permanently separated. One of them, named John Ma, is raised by his parents and grows up to be a concert pianist and conductor.

The twins accidentally switch places, causing confusion for both of them until they discover each other.
