What the sun sees when it gets dark: A girl is put to bed by her mother. She has many questions: Why does it get dark, what sounds can be heard at night, and what exactly happens when we fall asleep? Her mother's answers are loving, poetic, and leave room for interpretation. We accompany them as they go to bed, change clothes, brush their teeth, and say goodnight. There are also mental excursions into the land of dreams and to the starry sky. In dreamy images, the fascinating interplay between light and darkness unfolds.
