Einer wie Bruno

13-year-old Radost lives alone with her dad Bruno. He is not like other fathers, however, but suffers from oligophrenia: he has about the mental level of a ten-year-old. However, this reduction in intelligence has not prevented Bruno from being a great father to his daughter all these years. With Radost's awakening puberty, however, the first serious problems now reveal themselves. Radost becomes more and more aware of how much she is mentally superior to her father. Her responsibility, which until now has been a plaything of their relationship, becomes a great burden for the young girl, who actually wants to lead the normal life of a 13-year-old.
