In Northern Germany there is a mansion owned by the Drevis family. There used to be Monika, Alfred and the little girl Aya, a happy family who loved each other deeply. Then one day, Monika passed away from illness. Young Aya never saw her mother die. One year has passed since her death, and Aya and her father just live on. Alfred is always locked up in his basement "working", and Aya knows exactly what he does.
