The villainous entrepreneur Wolter Onix wants to build an asphalt factory on the site to pave all of the Netherlands. But Ernst and Bobbie are determined to stop him so Onix challenges them to complete some tasks. If they succeed within three days, he promises not to build the factory. Their mission: bring together a famous pop star, 40,000 concertgoers, and a golden microphone. It seems like an impossible task, but Ernst and Bobbie are determined to save the forest...
