Young Girls in Ecstasy
Les Petites Saintes y touchent (original)
The friends who attended the same boarding school meet and take turns telling their recent romantic experiences. These turn out to be as varied as they are crisp, from the initiation of a student by a teacher to the misunderstanding in the company of a lord, through the false English but true seducer, the swimmer obsessed with his physical condition and, obviously, love in a group (Le Chat Qui Fume).
