A small, peaceful village, bathed in sunlight. It is inhabited by simple, artless people. Giselle, a young peasant girl, is rejoicing in the sun, the blue sky, the singing of the birds and, most of all, in the happiness of pure, trusting love which has lit up her life. She is in love and is confident that she is loved. The gamekeeper, who is in love with Giselle, tries in vain to persuade her that Albrecht, her loved one, is not a peasant at all but a nobleman in disguise and that he is deceiving her.
