Die geheime Festung

For generations, the same scenes have been repeated at the holiday camp on the lake: The gang of children from the south shore fights with all conceivable means against the children from the north shore. As every year, there are fixed rules and truces, spies, forbidden weapons, permitted and illegal tricks - leeches, slow worms and frogs that are foisted on one's own party and then pretended that the others were the culprits. One thing is different this year, however: Sarah, the sister of the leader Marc, has fallen in love with Julien, of all people, the chief of the opposing side. When Sarah is suspected of being the traitor for whom Marc's gang constantly loses out, she flees with Julien into the forest in the middle of the night during a violent thunderstorm. Triggered by the torches of the other children, which the two are now looking for remorsefully, a forest fire breaks out.
