Georgette lives in Paris with her unexciting, effeminate husband Maurice. Suzanne lives across the street, spending her time reading romance novels while dreaming of someone more exciting than her own lackluster spouse Paul. The women happen across each other's husbands and begin their dream affairs. Four people, each cheating on a spouse, none of them aware that their own spouse is cheating--who will tire of the "excitement" first, and how?
