Carlo and Margherita: a happily married couple in their mid-thirties. They are in love, but they also harbour desires that stray beyond the confines of their bedroom: Carlo longs for the quiet beauty of one of his students, Sofia; Margherita fantasises about her physiotherapist, Andrea. Love, with its unassuming power, ultimately pulls them from the brink, but after eight years of repressed desires and the birth of a son, when the past resurfaces in the form of books sent anonymously, will love be enough to save them?
