Veteran French director André Téchiné (My Favorite Season) called on the younger, hipper Céline Sciamma (Girlhood) to help write this patient, psychologically credible portrait of two teenage boys who begin as schoolyard antagonists but end as furtive lovers. Damien (Kacey Mottet Klein), son of a military man and a kindhearted doctor, is bullied in school by Thomas (Corentin Fila), who lives with his ailing mother on their ramshackle farm. When the mother is hospitalized, her physician—Damien’s mom (Sandrine Kiberlain)—invites Thomas to stay with them and implores the boys to bury the hatchet, unaware that their mutual antipathy is a reaction to mutual desire. The screenplay is marred by clumsy foreshadowing and other contrivances, but Téchiné and Sciamma have tapped into something genuine: the deep confusion at the dawn of sexuality. “I don’t know if I’m into guys or just you,” declares Damien, articulating a question that perplexes them both.
