One Wild Moment (1977)

Plot

Pierre, a 44-year-old happily divorced man, heads to the picturesque Côte d'Azur with his teenage daughter and his friend Jacques, who brings along his own daughter, Françoise. While enjoying the sun-soaked beaches of Saint-Tropez, the friends engage in conversations about parenting and relationships. A spontaneous night at a party leads to an unexpected romantic connection between Pierre and Françoise. As their affair unfolds, Pierre wishes to end it, but Françoise professes her love and reveals their secret to her father—without mentioning Pierre's name. Jacques then seeks Pierre’s assistance in uncovering the identity of his daughter’s suitor, leaving Pierre in a moral quandary.
