El ángel exterminador

During a formal dinner party at the lavish mansion of Señor Edmundo Nóbile and his wife Lucía, the servants unaccountably leave their posts until only the major-domo is left. After dinner the guests adjourn to the music room, where one of the women, Blanca, plays a piano sonata. Later, when they might normally be expected to return home, the guests curiously remove their jackets, loosen their gowns, and settle down for the night on couches, chairs and the floor.
