Set in Mar del Plata during the brutal winter of 1985, underworld crime figure Margarita Di Tullio uses her pregnancy as a shield while building a clandestine nightlife empire around the cabaret Neisis, positioned as a refuge and a site of autonomy for women in a world dominated by men. As a wave of murders attributed to the “Loco de la Ruta” (“The Highway Madman”) spreads fear, Margarita discovers that the true monster is a web of collusion between the police and the judiciary.
