Chiennesophia, the self-proclaimed "chienne" (bitch), leads a pack of eager women onto the sandy shore of Berck's naturist beach. They shed their clothes, inhibitions, and any semblance of modesty, embracing their sexuality in the open air. The beach becomes a canvas for their desires, as they paint scenes of Sapphic passion with their bodies, the sun beating down on their naked, writhing forms.
