Marian Marzyński's documentary is a recording of circus artists' rehearsals. The director manages to show not only the physical effort of the acrobats, but, above all, their emotions and their striving for perfection and struggle with their own limitations. The camera focuses especially on the partnerships of the athletes working in pairs. It shows their interdependence on the way to the best possible performance of the trained acrobatic routine, based on the precise delineation of roles and mutual trust.
