Finja's reunion with Christian, the ghost of her love from the medieval times, brings her to the conclusion that the parents must atone for their past sins in order to weaken the Pied Piper. However, Finja's father Peter, along with Jannik and Sam's mother and Inspector Erik Zastrow, deny their guilt. Only the doctor Jamila, who is well versed in magic, supports the friends. Meanwhile, Ruben's time with the Pied Piper has left its mark.
