Aquatic Opening. It’s spring and water women, the undines, lay on the rocks and the grass to feel the first warm rays of sun. Everything has sprung and the flowers blossom with generosity to the light. One of them, Astrid, is not satisfied with the pleasures of nature and, instead of plunging into the waters of the river, she dives into an unknown book. Gradually, the laughter of the other girls and a little breeze that stirs the leaves are moved away from their senses, and Astrid is asleep.
