This time Ixi and his friends want to go high up: namely with mountain guide Reinhold and reindeer Greta, their visitor from Sweden, to the Zugspitze! With the right equipment and enough provisions, the troop sets off - through a rocky gorge in which it roars and roars like hell, across green alpine meadows with protected mountain flowers and happy bees to the scree field in front of the glacier and into the alpine high mountains. Along the way, the friends learn exciting, but sometimes also disturbing things about mountains and climbing, as well as nature, environmental and climate protection. When the friends almost have to give up shortly before reaching their goal, they get unexpected help from the shrewd mountain spirit Holladio. And when they are all standing happily at the golden summit cross guarded by eagles, it is clear that this was the best day of their lives! Once again, prominent athletes have been the inspiration. So similarities with living role models are definitely desired.
