Act One
A Small Village in the Rhine Valley.
By tradition at harvest time, the villagers gather at a different house each day to taste the new wine. We find them gathered at the cottage of the peasant girl Giselle. Count Albrecht, Duke of Silesia, has fallen in love with Giselle. He disguises himself as a peasant in order to court her.
Wilfrid, a gamekeeper, who also loves Giselle, suspects the true identity of his rival and warns her to be wary of the stranger. The peasants return with the last of the grape harvest and join in a dance with Giselle and the disguised Count. Laughing off her mother’s warning that her passion for dancing might be endangering her life, Giselle is crowned Queen of the Vine.
A hunting party led by the Duke of Courland with his daughter Bathilde, stops at Giselle’s cottage to rest. Wilfrid, learning that Bathilde is detrothed to Count Albrecht, reveals the truth to Giselle. The shock is too great for her and she dies, heartbroken.
