The first film in Romer's "Tales of Four Seasons" series. It was followed by "Summer Tale," "Autumn Tale," and "Winter Tale."
Jeanne teaches philosophy at a high school. Her boyfriend is away. Jeanne has keys to two apartments (her own and her lover's), but she doesn't want to return to either. Taking Kant's "Critique of Pure Reason" and Plato's "Republic," she runs off to a party, but even there she can't decide if she knows why she came or not. The heroine claims that if a person with the Ring of Gyges (an invisibility ring) on his finger followed all her words and actions throughout the day, he wouldn't be able to understand their meaning, if there is any at all. Meanwhile, a student named Natasha, who meets her at the party, is not against company and offers Jeanne to spend the night together in her father's Parisian apartment. A few days later, the girls became inseparable. However, it soon becomes clear that one of the reasons for their closeness is Natasha's desire to replace her father's current mistress with Jeanne.
