From NetFlix:
When Frédéric (Bernard Campan) and his family meet a gay man named Hugo (Charles Berling) while vacationing in the Provençal countryside, their lives are irrevocably changed, as the two men develop a strong yet unconventional friendship. Although Frédéric is happily married to his wife, Frédérique (Léa Drucker), his bond with Hugo challenges the strength of his marriage and ultimately inspires him to reevaluate his life.
This film is French in many ways: language, culture, beautiful photography,
symbols, ambivalence, ambivalence, and more ambivalence. Don’t expect
a definitive ending. You have to be in the mood for this one. And if you do
last through this dreamy, slow movie, please tell me how you interpreted the
relation between the straight husband (who truly loves his wife and family)
and the gay man when everyone meets on an extended summer holiday.
How did this end ?
