One night, the entire planet finds itself divided into two halves by a rainbow-sparkling Wall, very much reminiscent of the Northern Lights. From the north pole to the south, from satellites in orbit upward, to the deepest submersibles deep into the earth. People from different countries tried to break through it with both axes and a nuclear explosion, but all attempts dissolved in the bluish-turquoise glow of the monolithic structure. A day later, the Wall changed color to light pink, bifurcated along its length into two parts, and began to move uniformly to the west , and to the east. No one yet knew that it was intended to destroy seven billion people. In total, the Wall selected eight hundred thousand people to continue the human race. Mikhail did not know who would be among these lucky ones, but seeing how his daughter died due to the fault of the Wall, he is determined to deal with the incredible mechanism, there... behind the Wall.
