When Natalya V’yugina accepted an invitation from an unknown girl to come to Munich, she had no idea what awaited her in the house of Sonya Muravyova-Becher—who, for some reason, was posing as Natalya’s childhood friend. But mysterious events in the mansion, day by day, convince the girl more and more that this time she has gotten herself into not just criminal trouble, but… mystical trouble as well. Sonya tells her about a model of her house located in the attic. Since recently, dolls have begun appearing in it—copying real people. Natalya agrees to help Sonya investigate all the oddities, but she can’t stop asking one question: why did Sofiya only remember about her friend now—and call her specifically at the moment of trouble?
