Theft of funds during construction leads to the fact that the workshop being built by Alexey's company is falling apart right before our eyes. The accomplices who signed the acts for kickbacks turn away from the contractor. Moreover, he can betray the sawyers, and therefore becomes dangerous. The unnecessary witness must be removed. Alexey tries to hide in a remote village, in the house of his classmate, but ends up in 1988. Now the contractor, having found himself in the past, can rebuild the future. He can save millions of people, prevent hundreds of disasters. Or is it better to save his own marriage, which split many years ago, even before it began? Who needs the whole world if there is no one and only beloved woman nearby?
