A narrow circle of people becomes aware of a scientist who calculates future events. His latest “prediction” is the coming apocalypse. How to avoid imminent death? The professor points out a path along which several thousand lives can be saved, but at the same time he warns: everyone who will be saved must be kept in the dark until the last minute. Will those who know about the plan have the courage to condemn themselves to possible death for the sake of future generations? And if fate nevertheless leaves life, will the heroes be able to maintain friendship, remain human in a cruel, collapsed world? Especially when you remember that somewhere out there, on the other side of the globe, there is a civilization.
