The Earth is approaching the end of its existence - the Sun is going out, which threatens the death of all living things. In search of a solution to this problem, humanity sends a detachment of its representatives to another galaxy, to the planet Eva. Scientists, military men and ordinary workers will have to face a completely different form of life and enter into a difficult dialogue with it. Earthlings will see themselves as if in a merciless mirror, exposing all their shortcomings and vices that have not been eradicated by millennia of evolution. But it turns out that the residents of Eve also need the help of aliens from Earth, so that together they can earn a second chance at life and continued development.
