After his planetary success Snow Show that made him a star in the USA, Slave Polunin asked Terry Gilliam to join him to help him recreate an old show of his : Diabolo. It is a the genuine encounter of two geniuses, turning sometimes into a fight but always an adventure : on one side an American filmmaker and on the other side a Russian clown. They together experience the difficulty of making two creative worlds coexist on a stage, feeling always too small for them. Tension appears and evaporates around a glass of vodka, misunderstandings sap their motivations, anger rumbles like storms of frustration and finally explode into a tempest of laughter. We follow the first weeks of their collaboration up to Israel where the premiere of a unfinished show takes place. But is the show really on stage?
