From the IMDb description:
Léo is dragged to a nudist camping resort by his mother. Like most boys at the age of 12 or 13, being nude in public holds little appeal for Léo, who protests by wearing extra layers. Until he meets a certain special girl, who captures his heart and releases his inhibitions.
This short film is in French without subtitles so it can be tough to know what's going on sometimes, but I thought it was a nice film nonetheless that showed nudity in a very positive light.
