Due to an anonymous call, Inspector Glebsky travels to the hotel "Dead Mountaineer's." This hotel is situated in a mountainous region of a secluded valley in a European nation. Simply put, the hotel's name, "Dead Mountaineer's," refers to the fact that a climber perished here after falling from a cliff. He left only his faithful dog behind – a
St. Bernard called Lel. In the hotel there is a rather bleak portrait of the climber near which faithful Lel likes to sleep. Almost all of the lodgers are rather strange, especially Mr. and Mrs. Moses and Olaf Andvarafors. Later another strange individual materializes; Luarvik, who can not even utter a couple of words. Mr. Moses and Luarvik turn out to be
aliens and Mrs. Moses and Olaf are their
robots, although they look like ordinary people. And in the mountains they suffer a calamity. After a heavy snowfall, when the hotel is cut off from the outside world, a body appears at one point. Inspector Glebsky initiates an investigation, using all of his standard skills. However the investigation of the pseudo-murder of Olaf comes to a standstill. And when seemingly all intricacies of the plot unravel and the aliens can safely leave the Earth a military helicopter appears. The inspector has a chance to do great service to the aliens, but Glebsky behaves like a typical cop, subordinate only to common sense and official instructions which leads to the tragic outcome. At the end of the film the inspector is plagued by doubts whether he did everything he could. ==Cast==
