Dairy farming entrepreneur Primo Spaggiari finds himself facing bankruptcy and the disappearance of his son, who has been kidnapped for ransom. The kidnappers require a billion lira in order to free the sun. When the sun is said to have died, the entrepreneur puts up a fraudulent plan to save his dairy farm. Set in the Padan lowlands, this film is full of ambiguity and different tunes. With no gaps Bertolucci adds injections of irony and humour in the dramatic plot, producing a provisional work. Tognazzi in the role of the provincial entrepreneur gives a sharp and disturbing portrayal of Italian mediocrity.
