'Tajna dvorca IB' is a balletic musical, dialogue-less, propaganda rendition of Cominterne's Resolution used by Stalin to regain his rule over non-Soviet communist countries, especially Tito's Yugoslavia. This film can be considered as one form of Tito's propaganda response to Stalin's demands. Set in a metaphorical state, it describes the alchemical creation of Resolution in a desolate castle where enslaved Communist leaders work under Stalin's command. When the Resolution, in shape of a young woman, is released to the public, workers and citizens despise her and she returns to its' creators, her fate showing them that Yugoslav people are against Stalin's rule. This film remains a curio even for the most knowledgeable connoisseurs of Yugoslav film.

This puzzling experimental film is written and directed by Raymond Rouleau, who uses effects like changing color tones and masks to put across a drama within a dance drama. The set is a sound stage and the actors in this film are dancers on the stage, performing a mime-ballet derived from one particular legend. Both the enacted legend and the actual events affecting the dancers are parallel. The lead dancer Isa (Ludmila Tcherina) is still nursing her wounds after her first love left her to stand alone at the altar. Now one of the dancers wants to expand his relationship with Isa -- and soon after, the cad who jilted her suddenly shows up again. Tragedy follows closely behind.
