The story of two friends and managers of a mountain hut. The central theme of the film is nature conservation and environmental protection. Friends Mišo and Dušan, who love the Tatras, try to preserve "their" valley as one of the last corners of nature untouched by tourism. They do it with sincere enthusiasm, but only with the means at hand. They settle accounts with sneaky hikers.
Unfortunately the movie Stratená dolina is not yet available on Disney Plus.
