26 years later, the twins' (Jackie Chan) lives intersect again: Bok Min and his best friend Tarzan (Teddy Robin) get mixed up with a dangerous gang, while Ma Yau prepares to conduct a major concert in Hong Kong. In addition, the twins gain romantic interests: Bok Min meets Barbara (Maggie Cheung), a club singer Tarzan is interested in, and Wan becomes acquainted with Tong Sum (Nina Li Chi), a young woman from a respectable family who has a secret passion for fighter types. Eventually, the twins meet and discover that they share a strange connection with each other. As a result, a string of hilarious mix-ups ensues when Ma Yau is accidentally enlisted by the gangsters to participate as an escape driver in the liberation of none other than Crazy Kung; Bok Min in turn is forced to conduct Yau's concert (which becomes a smash hit despite him having absolutely no musical talent); and the two of them end up with the other's girl as their respective love interest.
