context: Laurent Chevalier is a nearly 15-year-old boy living in Dijon in 1954, who loves jazz, always receives the highest grades in his class and who opposes the First Indochina War. He has an unloving father who's a gynecologist and an affectionate Italian mother, Clara, as well as two older brothers, Thomas and Marc. One night, Thomas and Marc take Laurent to a brothel, where Laurent loses his virginity to a prostitute before they are disrupted by his drunken brothers. Upset, he leaves on a scouting trip, where he catches scarlet fever and is left with a heart murmur.After Laurent is bedridden and cared for and entertained by Clara and their maid Augusta, he and Clara check into a hotel while he receives treatment at a sanatorium. He takes interest in two young girls at the hotel, Helene and Daphne, and also spies on his mother in the bathtub. Clara temporarily leaves with her lover, but comes back distraught after their breakup, and is comforted by her son. After a night of heavy drinking on Bastille Day, Laurent and Clara have sex. Clara tells him afterwards that this incest won't be repeated, but that they shouldn't look back on it with remorse. Afterwards, Laurent leaves their room, and after unsuccessfully trying to seduce Helene, spends the night with Daphne.Jazz music by Charlie Parker and Dizzy Gillespie, along with books by Bataille, Proust and Camus, feature prominently in the film.
