It is August 2018. Three free skiers, the Red Bull athlete Fabian Lentsch and the two alpinists Stefan Ager and Andreas Gumpenberger, are on their way to the Bürser Mittagsspitze in the Brandner Valley. In general, this mountain tour is nothing special, however, in a few months, this should become a place where history will be newly written. They plan to fly with a Zeppelin over the summit, to abseil down to the summit and to ski down the slope. This will be an event like no-one before, where every millimetre and every gram will be decisive about success or failure.
