Plot synopsis: Pasi, a lonely but kind-hearted designer of artificial animals, lives in a world where nature is just a memory and human well-being is organized with perhaps too much care. One day, Pasi accidentally finds the world's last living squirrel and meets Emilia, an official who enforces the rules of well-being. Pasi decides to defy society's rules and help the squirrel, but something unexpected happens—the squirrel becomes depressed and Pasi falls in love.
