Mia has an idea for a musical. The best thing is that this idea is to save the Leo Weiß School from the impending closure. But the "potato salad" staging about the past zombie apocalypse causes great confusion.
The school year is over and for a diverse group of carefree kids, soccer is king! These kids believe that they are the local gold team and there is nothing they like more than improving their game. "If you want to be cool, you should be wild." However, the relentless rain turns their field into a swamp, so they have to take an unexpected break. And when the sun finally comes, a gang of older, bigger and dumber boys has just taken over the field. They won't give it back unless they lose a match against the kids.
