The IMDB summary reads "A young tourist is sexually assaulted by two men in the countryside. After she manages to escape, a party of local hunters agree to track her in order to cover up the scandal."
The woman raped is Mimsy Farmer, who is excellent in the role, which doesn't require much dialog from her but does require her expressions. There is no nudity in this movie.
She's raped. One brother (Jean-Pierre Marielle) holds her down while the other brother (Philippe Léotard) screws her. Marielle here perfects the part of a physically intimidating leering lout. The younger Léotard, who was very capable in all his movies, could not be better as ruled by his dick when drunk and almost immediately guilt-ridden over what he has done.
They are part of a larger hunting party out for wild boar, and this includes such standout actors as Michael Lonsdale, Michel Constantin and Paul Crauchet.
These middle-class bourgeois, some with aspirations for politics and aristocracy, one a war hero, are revealed to a man as utterly bankrupt morally and cowards. There is not a "man" among them who will stand up against the rest and break from their cover-up. The pillars of respectable society are shown as loathsome liars hiding behind their false fronts.
Claude Renoir was cinematographer and Serge Leroy was director. Sometimes outdoor pictures lose control to the wildness of the settings, thereby taking on an amateurish quality. This is never the case here. We are in some country settings, some unstructured, but they are employed to intense effect.
One could have a marvelous film festival from this era that showed this film along with L'Agression (1975) and Le vieux fusil (1975). One could add in a number of Delon pictures in the countryside, such as "The Burned Barns" (1973) and "La veuve Couderc" (1971). Top it off with Gabin as patriarch farmer in the great "La Horse" (1970). L'agression is a city-road movie, not in the country; but it carries the theme of repressed middle-class violence.
