In a Portuguese apartment building, two couples share the same structure, yet live in entirely different universes. Iara and Lusa, a Brazilian couple, face the silence and strain of a marriage marked by routine and an emotional distance from each other and their homeland. Upstairs, Pedro and Inês, a younger Portuguese couple, lead an intense relationship fueled by energy, impulsivity, and a still-vibrant intimacy. Between thin walls, sharp banter, and cultural misunderstandings, their co-existence becomes a stage for laughter, unease, and unexpected revelations.
