Lucía (Malena Alterio) loses both her job and her emotional footing after her employer collapses under fraud allegations. Caring for her difficult father Juanjo (Manuel de Blas) while driving a taxi across Madrid, she fixates on Braulio Botas (Rodrigo Poisón), an actor connected to a fleeting romantic memory and the aria "Nessun Dorma." Her search reshapes her routines, appearance, and sexual behavior. She forms a tense friendship with theater producer Roberta (Aitana Sánchez-Gijón), who promises access to Braulio while quietly studying Lucía's confessions and vulnerabilities. As betrayal accumulates from every direction, Lucía begins treating the city itself like a stage where private humiliation demands an audience.
