The ambassador of the Latin American republic of Miranda (Fernando Rey), M. Thevenot (Paul Frankeur), his wife Simone (Delphine Seyrig) and her sister Florence (Bulle Ogier) arrive for a dinner party at the house of Alice Sénéchal (Stéphane Audran) and her husband Henri (Jean-Pierre Cassel), only to learn that they were mistaken about the date. In director Luis Buñuel's surreal fantasy, the six bourgeois friends repeatedly gather for a dinner that never quite arrives.
