Les Amoureux de Marianne(1953)

Gaston Duboutois and Catherine Berton love each other, and are about to play Romeo and Juliet in their small provincial town. The industrialist Duboutois is opposed to his accountant Berton, both of whom are running for parliament. Tempers flare and invective quickly escalates. In the end, Duboutois wins and Berton loses his position. Although futile and foolish, it's the excellent Mme Duboutois who brings peace to the situation, brings about reconciliation and helps the two children to unite.
