Act 1:
A village in the midst of celebrations
Giselle, a pretty village girl, has fallen in love with a handsome young man who comes from elsewhere. She knows nothing about him. He says his name is Loys. However, Hilarion the gamekeeper, whose shrewdness is made all the sharper by jealousy, suspects that he is a nobleman. Everyone is swept up in the dance. Waltz

Giselle’s mother worries that her daughter’s fragile health will not withstand her passion for dancing and, recounting the fate of the wretched Wilis – maidens who having died before their wedding day are condemned to dance every night until dawn – fears a similar end for her daughter. Giselle laughs off her mother’s concerns and continues dancing with the handsome young man. She is crowned queen of the festivities.

The Peasants’ pas de deux (also known as “the Harversters’ pas-de-deux”)

The Prince of Courland happens to pass through the village with his entourage. He stops in front of Giselle’s house and asks for something to drink. His daughter, Princess Bathilde, is engaged to Albrecht, Duke of Silesia, who is none other than… the young man whom Hilarion has just unmasked, having discovered the coat of arms on the sword of his rival. Giselle – shocked by the revelation – loses her mind and dies.

Act 2:
The forest at midnight: a tombstone topped with a cross.
Several white shades suddenly streak furtively by, then return. Who are these ethereal creatures? They are the Wilis, the souls of young maidens abandoned by faithless lovers. They reap their revenge luring young men to their death by night in the world of shadows. Myrtha, their queen, gathers them together to welcome a new companion into their midst: Giselle appears, shrouded in a deathly pale veil.

Dance of the Wilis

Albrecht arrives to place flowers on Giselle’s grave. He sees the ghostly-white vision of his beloved floating above him and tries to catch hold of her, but the apparition continually escapes his grasp. Finally, it flees. Entranced, he follows her. The foolhardy Hilarion arrives and the Wilis lead him into a feverish yet fatal dance: he is their first victim of the night. Albrecht is set to suffer the same fate.

Giselle implores Myrtha and the other Wilis to show clemency but they remain inflexible. Condemned to dance until exhaustion, Albrecht finds support in Giselle’s love: momentarily united, they dance desperately. Soon, the first light of day forces the ghosts to flee. Giselle, in turn disappears, leaving Albrecht to real life.
