Mr. Conductor's sister visited him at the station. At the same time, Kara's grandfather Harry also came for a visit. He built a small racing car for Kara and wished that she would participate in the annual race. However, Kara had other plans and didn't want to do everything that Harry wanted her to do. Meanwhile, Mr. Conductor got very upset when his sister used her magic to play tricks on people. During the day of the race, Kara thought about how she had been unfair to Harry. So he decided to participate in the race at the last minute. Unfortunately, the wheel on her car was broken. Sister Conductor decided to help as she and Mr. Conductor flew on a plane and drop a useful tool in Kara's pocket. Kara used the tool to fix her car, and she managed to won the race. At the end, she dedicated the trophy to her grandfather Harry.
