Turbo the Mountain Fox is on summer vacation at the Finnbu mountain lodge, and today he has to refresh and repaint the red T markings along the path up to Djeveltunga. It's an easy task – he can see the peak from the cabin! But the weather changes quickly in the mountains, and when the fog comes, Turbo and his friends lose their way. Or is it the map that's wrong? Suddenly everything is unknown – and then they hear some scary sounds ...

Fortunately, it all goes well in the end, and maybe Turbo has learned something along the way.
