It is midnight in a dark wood. A pool of water is in the distance. Gamekeepers enter. Hilarion warns them that the spot is haunted by the Wilis. The gamekeepers run away. The Queen of the Wilis rises from the weeds to call the Wilis together. Giselle is about to become one of them. She rises from her grave. She dances. Albrecht enters to pray at Giselle's grave. He sees Giselle. They dance. The Wilis trap Hilarion. They force him to dance. They throw him into the pool to his death. The Queen of the Wilis wants Albrecht to die too. Giselle does not want this. She wants to save his life. Day breaks. The Wilis disappear. Giselle returns to her grave. Bathilde and the courtiers enter. They are looking for Albrecht. He falls into their arms exhausted.
