French stage actor Louis Ducreux makes his film debut as a 76-year-old traditionalist painter, Monsieur Ladmiral, in this bittersweet portrait of a brooding artist. A widower, Ladmiral lives on an estate in the countryside near Paris with only his housekeeper, Mercedes (Monique Chaumette), and his paintings to keep him company. The action of the film takes place on a bright autumn Sunday in the early 1900s when Ladmiral's son, Gonzague (Michel Aumont), and Gonzague's wife, Marie-Therese (Genevieve Mnich), come out from Paris with their three children to visit the old man. While making small talk with Gonzague, Ladmiral hints ever so subtly that his son has become too bourgeois, too conformist, too accepting of the status quo. Apparently, Ladmiral doesn't want his son to face what he is facing: self-recrimination for failing to take risks, failing to go beyond the bounds of tradition.
Theatrical producer Max Bialystock (Zero Mostel) was once the toast of Broadway. Now he lives in his seedy office, cadging cash contributions from wealthy old ladies in exchange for sexual favors. Even worse, he's reduced to wearing a cardboard belt. Max's new accountant, Leo Bloom (Gene Wilder), the soul of honesty, suggests that Max produce a hit to try to recoup his losses, but Max knows that it's too late for that. Offhandedly, Leo muses that, if Max found investors for a flop, he could legally keep all the extra money. Suddenly, Max's eyes light up – and in that moment, Leo Bloom is gloriously corruptible. "I want everything I've ever seen in the movies!" cries Leo as Max embraces him. Together, Max and Leo conspire to select the worst play, the worst playwright, the worst director, and the worst actor to collaborate on their guaranteed flop.
