A year has passed since the talented mystery writer Agatha Sever, accompanied by her assistant Marusya, took an unforgettable trip to an island in Lake Ladoga. The writer found herself at the center of a twisted criminal story that formed the basis of her new bestseller. Before she can reap the rewards of her success, Agatha returns to the spot where it all happened. The island’s residents give an unfriendly welcome to the celebrity who caustically portrayed them all in her book. Agatha learns that her own aunt Sofia lives there, known by the nickname «the witch dollmaker». Many years ago, Sofia lost her six-year-old daughter Inga in the forest and never recovered from the tragedy, even in old age. Agatha does not have time to meet Sofia: the elderly recluse dies on the eve of her arrival. The writer must uncover long-standing family secrets and clear herself of the murder charges brought against her.
