The two-part television film "Northern Lights: The Witch’s Dolls" from the detective series about writer and amateur sleuth Agatha Sever, set in Karelia on the shores of Lake Ladoga, becomes one of the most frightening and mysterious cases in the woman’s career. Agatha has had to deal with many different problems, but this latest incident becomes the most personal one for the writer. Returning to the Karelian coast with her assistant Marusya a year later, Agatha finds her elderly aunt Sofya in critical condition. The old woman was never able to recover from the loss of her young daughter and lived a long life without ever finding happiness. Agatha’s aunt had an unsavory reputation and was considered a witch, and the locals greeted her death almost with relief. The islanders have little more regard for Agatha herself, viewing her as an arrogant city girl, and when Sever becomes a suspect in Sofya’s murder, they refuse her any support. However, Agatha is used to relying solely on her own strength, and the need to get to the true causes of her relative’s death becomes a matter of honor for the writer.
