Ten years ago, Isa von Gems, daughter of the von Gems brewery dynasty, was last seen at Lotheim high school’s summer festival, after which she disappeared without a trace. There was no good-bye note, no ransom demand, nor was an accident reported nearby or a body found. Isa was just gone. It was a shock for her family and friends, but eventually life went on, as it must – until now. Peter Wolff is absolutely convinced he has seen Isa one night in Lotheim, outside of her family’s brewery.
