The bright community is preparing for an important event - the Mermaid Circle. Initiated magicians from Zarechye, Divnomorye and Kitezh will gather in Suzdal to experience power and luck. The names of Mitya and Seva appear on the list of participants. Polina also goes to Suzdal. Despite the fact that the Water Witch is increasingly experiencing attacks, she has a special role in competitions. Friends rejoice at new adventures and victories and have no idea what awaits them at the end of the Mermaid Circle, when two worlds - the living and the dead - come into contact. And victory does not mean that you will remain in the world of the living.
