Rocca Changes the World

A German astronaut on spatial mission can only video-call with and worry about his cocky daughter, nicknamed Rocca, who officially lives with her old-fashioned grandmother in Hamburg, but takes no notice of gran and risks being placed in social custody after her bad ball and hospitalization. Rocca constantly challenges rules and authority, also at school, while flaunting what she learned from father. She pretends to solve administrative problems by signing papers instead of adults, and invites a homeless man to act as her token guardian.
