By 2134, humanity gains the opportunity to correct the events of the past. This avoids wars, violence and disasters. But it's not that simple. In the most closed and mysterious city on Earth, where the Holy Machine - a device that changes reality - is located, a series of strange events occur that disrupt the usual work of city services. The final fate of the city will be decided by the friendship of a man and an og - a creature with a non-human psyche who managed to escape from his reservation.
