When Natasha Vyugina accepted an invitation from an unknown girl to come to Munich, she had no idea what was waiting for her in the house of Sonya Muravyova-Becher, who for some reason was posing as Natalya’s childhood friend. But the mysterious events in the mansion convince the girl more and more every day: this time, it seems, she has gotten into not just criminal troubles, but also... mystical ones.

Natasha agrees to help Sonya deal with all the oddities, but she is tormented by just one question - why did Sophie only now remember about her friend and call her in difficult times?..
