The peasant girl Giselle discovers the true identity of her lover Albrecht, and that he is promised to another. Giselle kills herself. Her soul enters the ranks of the Wilis: shades of young women who died before their wedding day. All men that come across their path are compelled to dance themselves to death, and Albrecht falls into their trap. Giselle’s intercession saves Albrecht and releases her soul from the Wilis’ power.
