One day, Ulyana, a 10th grade student, runs into a witch named Ruta, who forces the girl to make a deal with her. Under the terms of Ruta, Ulyana must bring her the things of three dead people. In return, the girl's mother will remain alive, and the main character stops seeing the deaths of loved ones. The girl meets other "servants" of the witch, and also meets those who managed to escape from her - and understands that the only way to survive in this game is to defeat the witch.
