In the bustling heart of Barcelona, 1982, Rosa, a vivacious 31-year-old, stumbles upon her husband's secret world. Hidden in their apartment, she finds a well-worn VHS tape, labeled "31 - verano 1982." Intrigued, she pops it into the VCR, revealing a side of her husband she never knew existed. The footage, grainy yet intimate, shows him in a dimly lit room, his body glistening with sweat, pleasuring himself with a fervor she's never witnessed. The camera pans out, revealing a collection of similar tapes, each with a date and location - "24 - Madrid," "17 - Valencia." Rosa, feeling a mix of shock and excitement, begins to explore her own desires, inspired by her husband's hidden passion.
