On a forest home trip with her classmates, ten year old Marlene is struggling with her early pubescent, changing body. She feels ashamed of her boobs growing. Therefore, she avoids to shower with the other girls and hides her evolving body under large sweatshirts. When the other kids start making fun of an oddly developed tadpole at the forest home museum, Marlene is weirdly identifying with it and decides to set it free.
