Alice has grown up and is increasingly pondering what she truly feels for her friend, the investigator Vasya. Meanwhile, a new victim appears in the case of the "swamp maniac." Fearing for Vasya's life — he is being haunted by the ghost of the deceased — Alice gets involved in the investigation again. In addition, she will have to get to know Lena's parents better, but Alice has no idea what role this family has played in her own life.
