The Earth is in the extreme stage of an allergy to human activity. It has been holding itself back for a very long time, but now there is very little time left before it "sneezes" and humanity suffers the fate of the dinosaurs. The only one who can warn people about the danger and fix something is Stas. A simple miner who dreams of moving to the sea. He never bothered about ecology, but he is the one who begins to hear the voice of the Earth.
This happened when the daring eco-activist Lena decided to independently explore the abandoned part of the mine. Because of what happened the collapse that buried Stas, after which he established contact with the Earth. Now Stas must first convince Lena, and with her the whole world, that "a" - he is not crazy and, indeed, hears the Earth and "b" - the Earth warns that humanity has very little time left to save it and, along with it, itself.
