Dietmar has had too much fun at home, so he moves into the guardhouse for a while. The "village witch" Mrs. Rosen says that the long-dead Count of Havelstein appeared to her at his castle. For Hengasch, this means that the prophecy will come true: first darkness, then thunderstorms, then time stands still and in the end death will come to Hengasch. Sophie laughs at the belief in witches. Dietmar and Bärbel are scared. And behold. One after the other, the lights go out in the Aubach Inn, it starts to thunder and the clock at the guardhouse stops. When the death of the countess is then reported at the castle, Sophie begins to investigate. At the castle, Bechermann determines that the dead woman probably had a heart attack. However, the dead woman's wide-open eyes indicate a great pre-mortal terror. When Dietmar finds out that the countess wanted to leave money to the manager Tölke, who in turn is addicted to gambling, it becomes clear that Tölke and the housekeeper Waltraud have been working together. Sophie, on the other hand, is kindly driven home by Jan Schulte after her car breaks down. The subsequent tour of her property ends in Sophie's bedroom, helped by the predicted thunderstorm. Sophie enjoyed the night and would like to continue it, but Schulte realizes that he does not want a relationship. Sophie reacts completely irritated, because she had not even thought about a relationship.
