The ballet is about a peasant girl named Giselle, who dies of a broken heart after discovering her lover, Albrecht, is betrothed to another girl. The Wilis, a group of mystic and supernatural women who dance men to death, summon Giselle from her grave. They target her lover for death, but Giselle's great love frees him from their grasp. The Wilis are particularly haunting characters. They are the spirits of virgin girls who died before they married. At dawn, the spirits of all the girls and Giselle disappear, leaving only a deep imprint on Albrecht's memory as an eternal regret for a lost love that is stronger than death...
