Ten-year-old Strollica discovers that a wind power plant will be built in her favorite park. She's worried because she notices birds don't sing anymore and the landscape doesn't look very beautiful anymore. She's determined to demolish the windmill herself. The windmill, in turn, is upset and invites Strollica to visit its inner mechanism to understand renewable sources of energy. The child understands, yet she laments the damage to her own environment. An agreement will be reached and the plant will be moved elsewhere
