"If you fail, we will never forgive you!" Angrily, the generation of young climate rebels appeals to adult reason and makes 2019 the year of their protest. The reason: our future is threatened by global warming. The Swedish student Greta Thunberg has risen to become the leading figure of the worldwide movement that has shaken up the general public with civil disobedience, strikes and demos. Director Jim Rakete asks some of the most prominent faces of the climate rebellion about their motives. They receive support in the film from punk rock legend Patti Smith, filmmaker Wim Wenders and many more.
