Sometimes you just need to run away

Finn, who is about to turn ten, is taking the train alone for the first time. His mother is waiting for him at the station in Berlin. But on the train, the boy's backpack is stolen. And he is left without a ticket, phone, and money. The conductor removes him from the train and hands him over to the police. On the way to the station, the police car collides with a truck. And while the drivers are sorting things out, Finn and Iola — the girl from the truck — decide to run away from the adults. That's when the adventures begin.
A tractor ride and an overnight stay in a hunting lodge — that’s cool! But how will the children return to their parents without money and a phone? And what awaits the thief who robbed the boy on the train?
