Set against the sun-drenched, picturesque shores of a secluded French freshwater lake, Franck spends his summer days cruising for casual romantic encounters. A haven for gay men seeking discreet trysts in the surrounding woods, the beach serves as a communal space for both relaxed sunbathing and intense, silent flirtations. Franck quickly forms two distinct bonds: he strikes up a platonic, philosophical friendship with Henri, a brooding, solitary older man who comes to the lake solely to observe and escape his loneliness, and he becomes utterly captivated by Michel, a dangerously handsome, magnetic regular.Franck’s attraction to Michel deepens rapidly into an obsessive passion, driven by the intense physical chemistry they share. However, this desire is immediately complicated by a dark and harrowing incident. One afternoon, while swimming away from the crowded shore, Franck watches in concealed horror as Michel holds his current lover, a gentle man named Guy, underwater, deliberately drowning him. Instead of fleeing or going immediately to the authorities, Franck’s infatuation overrides his moral compass.

The police arrive to investigate Guy’s
mysterious disappearance, questioning the sunbathers and casting a pall of suspicion over the lake.

Inspector Damerval questions Franck more intensely, closing in on the truth. Recognizing that the net is tightening, Michel eliminates the primary obstacle to his freedom by brutally murdering Henri in the woods. Franck discovers Henri’s lifeless body, realizing
the true cost of his complicity. Terrified for his own life, Franck flees into the pitch-black forest to hide. In the final, haunting moments, Michel searches the dark woods, calling out Franck’s name. Franck stands frozen in the shadows, paralyzed by a devastating mix of lingering desire, grief, and absolute terror, unsure whether he is being hunted or saved.
