The main hero is an ordinary person. He works as a lathe operator, trains in hand-to-hand combat for pleasure, and doesn’t expect anything supernatural.
A terrorist attack on the subway flips his life around and sends him back to the past.
Is it an accident or the actions of outside forces?
But he has to live and survive in wartime conditions.
Everything the main character can rely on is his own strength and the skills acquired during training.
A prisoner taken in the first battle determines the further fate of the main character—he is assigned to a group of saboteurs. Special services are watching him; it turns out he is not the only one who “failed.”
