The history of the connection and interaction of two worlds: real and magical, rational and mystical, the world of people and the world of spirits. In the 50s, exiled to the European part of the Union, the great Tunguska shaman takes an ordinary teenager as his disciple. After some time, the shaman and the boy disappear. Already today there is theft in the local history museum. An old shaman's tambourine is stolen and the case is entrusted to Major Kolchanov. A simple matter turns out to be a multi-layered cake - three generations of shamans are looking for the sacred tambourine “Fire of Haglun”, ancestral revenge and blood ties with the Monastyryov family make them hostages of the prophecy of the Divine Warrior of the Silent sect, which longs for the revival of a dying people through a new Foremother.
