In the heart of Paris’s gay scene, Jim reigns supreme: the ultimate Gym Queen, influencer, and object of universal thirst. But when a bizarre virus called Heterosis starts turning gay men straight, his reign ends overnight. Unfollowed, abandoned, and stripped of status, Jim is left with just one unlikely ally: Lucien, a devoted scrawny twink with more loyalty than clout. Together, they plunge into the queer chaos of the Marais, chasing a rogue doctor rumored to have a cure.
