Outland

A person from our time experiences visions of the past - and thinks he is sick. Medications do not help, he turns to the shaman. The shaman understands what is going on and talks about the battle that happened 30,000 years ago. The battle between the great hero and the two Sisters of Chaos. One of the Sisters controlled the Light of the Sun, and the other - the Darkness of the Moon. The sisters lost the battle, and the hero imprisoned them. The shaman sees that a person with visions is an incarnation of the hero, and visions can mean that the Sisters managed to escape from prison.
