Radish Village is a remote small town with a long history, where the residents are all sorts of bizarre modified cars. However, at some point, the town became plagued by chaos and rampant banditry. One day, four companions arrived: the double-headed repair cars Dana and Erna, the all-purpose rescue vehicle Lao Han, the cunning and lazy jack, and the vacuum cleaner Nier. Together, they opened a roadside Q Car Bar, specializing in car repairs. Here, they sing, dance, play, and joke around. As the car bar thrives, one incredible and amusing story after another unfolds at the Roadside Q Car Bar.
