Widely considered to be one of the masterpieces of the French New Wave, this existentialist fantasy tale is the result of a collaboration between director Alain Resnais and French novelist Alain Robbe-Grillet. In a luxury hotel somewhere in Europe, an unnamed man (Giorgio Albertazzi) attempts to persuade one of his fellow guests, a similarly unnamed married woman (Delphine Seyrig), that they have not only previously met, but that they had an affair and made plans to elope together. The woman, however, does not appear to recognise him, and so begins a cinematic puzzle that questions the very nature of truth and narrative.
