A fairy tale film about the clever tightrope walker Tibule, who fights alongside the armorer Prospero and all the working people against the tyrants, the three Fat Men, who rule the state until the young heir Tutti comes of age. The freedom fighters are aided by the kind Dr. Gaspar and the brave acrobat girl Suok, who has to pretend to be a doll to sneak into the palace and free Prospero.

This lavish Soviet/Czech co-production is based on Fyodor Dostoyevsky's famous novel, The Gambler, which tells the story of a Russian living in Germany, in a gambling resort. This film is set at the turn of the century, and was filmed in Karlovy Vary (Carlsbad), Czechoslovakia. Played by Nikolai Burlyayev, the gambler succumbs completely to his addiction, using up every resource he has (human, spiritual and financial) in his wagering, finally becoming a rootless drifter.
