You can't see the elephants

When thirteen-year-old Mascha is sent to her grandparents' for the summer, she spends her days bored and lonely at a nearby playground. There she meets Julia and Max, two young siblings who are incredibly shy and withdrawn. Mascha soon begins to suspect that they are being physically abused by their father, a prominent member of their small community. She tells her grandparents and the authorities, but they all refuse to believe her. Mascha can't let the abuse go on, so she takes matters into her own hands.
