Kleine Kreise plot
Paul is extremely adept at setting up extremely unsuccessful ventures. He lives in a garage between a trading company and a furniture center. Since his wife left him, he doesn't see his son Niki much anymore. When Niki is with him for a weekend, the two go for a few laps in a race hall with a kart. They soon get a taste for it. Together with grumpy old shopkeeper Karl, whom they abuse as a sponsor for their adventures, they gear up for an entire summer vacation from race to race. It soon becomes clear that they don't stand a chance in the matches, but Paul is far too stubborn to give up just like that.
