Johan Petit collects sentences. Sentences he hears at barbecues and family parties, at home and on the street, at the café and in the waiting room. O Superman is about the small gesture, about love and trust. For an hour and a half, Johan digs into his memories. He talks about falling on the ice, ecological sniffing, and knitting a sweater. About failing and still continuing to believe that everything will always turn out well — even if it doesn't turn out well. Muzikanten Kato Van Ermen and Engel Peet provide musical rest in the chaos of Petit's head.
