Our leads are Paul (Brando) and Jeanne (Maria Schneider, at the time a somewhat inexperienced actress). After several near-meetings and glimpses on the street and in a bar, she goes to rent an apartment that he has already entered. Without knowing one another's names, or anything else, the two engage in a burst of passionate, impromptu sex, before embarking on a relationship centred around the apartment, despite troubles in their personal lives and an obvious age gap of at least twenty years.
