This is a crime / mystery thriller with surreal and psychedelic science fiction overtones based on a book Inspector Glebsky's Puzzle by the Strugatsky brothers. The screenplay was also written by the brothers and it differs from the book. The less you know about the movie the better starting point you have. The film is based largely on the mystery of what's happening to the people of Dead Mountaineer's Hotel. Is everything what it seems? Who's dead or who's not?
