47 children are given free rein on an abandoned construction site in Copenhagen, where nature has long since taken over. Here, they will go to school for ten weeks and discover what nature has to teach them. The film is told through scenes with the children, but also with nature's voice as a continuous narrator: "For what does it mean to learn something? How do you know what you've learned from feeling my wind in your hair or my rain on your cheeks? How can you measure what you sensed in your belly as you sat in the top of my tallest chestnut tree? Where does it settle in you?"
