Twin Dragons

In 1965, a Hong Kong hospital becomes the scene of a chaotic moment as Crazy Kung is being transported and escapes. He attempts to seize one of the newborn twins, causing a panic that leads to permanent separation. Ma Yau is taken to America, while Ma Wan is raised locally.

Crazy Kung’s breakout in the hospital creates the moment that fixes the twins’ fates. The ensuing chaos ensures the family is torn apart, and the twins never know each other. The episode seeds the lifelong divergence of two very different lives.

Ma Yau grows up in America and channels his talent into music. He becomes a concert pianist and conductor, pursuing a high-culture path far from his brother. He remains unaware of the twin across the ocean.

Ma Wan is raised in Hong Kong by the alcoholic Tsui, growing into a street racer and martial artist. He lives on the edge of danger, completely unaware of his twin. The brothers’ parallel lives set the stage for the coming clash.

1991 marks 26 years after the twins’ separation, as Bok Min and his friend Tarzan get tangled with a dangerous gang while Ma Yau prepares to conduct a major concert in Hong Kong. The two threads run in parallel, hinting at a comic collision of identities and loyalties. Both brothers are unknowingly stepping toward the same fateful encounter.

Bok Min meets Barbara, a club singer, while Tarzan pursues his own romantic interest. Ma Yau becomes acquainted with Tong Sum, a young woman from a respectable family who secretly loves fighter types. The romances deepen the comic chaos that follows.

Comedy erupts as Bok Min is forced to conduct Ma Yau’s concert, turning a prestigious performance into a chaotic but successful show. At the same time, Ma Yau is recruited by gangsters to serve as an escape driver. The mistaken identities drive the plot toward a clash.

The twins end up with the other's girl, worsening the romantic entanglements. They must navigate the gang’s schemes while pretending to be each other. The mix-ups fuel the film’s humor and energy.

Gang members kidnap Tarzan to force Ma Yau to surrender a briefcase that Ma Yau had accidentally nabbed. The stakes rise as the mislaid item becomes the key to Crazy Kung's release scheme. The twins realize their fates are tied to this single object.

Realizing they must act together, the twins join forces to defeat the gang and reclaim their lives. They plan and execute bold moves, using each twin’s strengths to outsmart the criminals. The collaboration marks a turning point in their shared fate.

The confrontation culminates in a dangerous chase at a vehicle testing center, where Crazy Kung dies in a runaway crash test car. The gang is defeated and the twins’ lives begin to normalize, with their odd bond only stronger. The audience is left with a mix of relief and humor as the threat ends.

The film ends with the impending double wedding of the twins to their partners, and Bok Min finally meeting his real parents. Bok Min proves hesitant, prompting Ma Yau to search for him. A final gag lands when the wedding guests cannot tell the two twins apart.
