There was an old man who went to Hong Kong History Museum to see the tram. He sits on the driver's seat, trying to have a taste of driving tram again, after his retirement from a tram driver years ago. Suddenly, the museum's wall cracked, and the tram started moving. As the tram traveled, the old man became younger, and more and more passengers appeared. He cherishes his tram very much. After he has completed his work every day, the man cleans up the body of the tram. He also sticks a unique logo on to the tram. One day, when he was driving a tram, the buildings next to the tram gradually disappears. After then the tram has traveled for some distance, a lot of buss overtake the tram from behind. New buildings also appear to replace the older. Finally, the last tram which is driven by the man disappeared, and the man wakes up from his memory.
