On a rainy night at the Foire du Trône funfair in Paris, a young man on roller skates meets two attractive women enjoying the fairground attractions. A spontaneous walk beneath a shared umbrella, playful flirting, and a sensual dance on a carousel quickly spark an irresistible attraction between them. The following day, what begins as a casual lunch meant to continue their encounter takes an unexpected turn when another group arrives. New attractions emerge, partners begin to change, and social conventions gradually fade away, leading the characters through an increasingly daring series of encounters that culminate in a large-scale orgy where everyone eventually comes together.
