Once - and the electricity goes out. And with it, it seems, the entire civilization is disappearing. There is no running water, heating, television, Internet, computers and cell towers do not work. How did it happen? Why? How long will this continue, or will it always be like this now? If you are not at all prepared for critical situations and are lost among regional villages and forests, finding out all this will not be so easy. First, you will have to try to survive, learn to cope without reference books, without an omnipresent network, without the advice of distant friends and strangers, without the usual auxiliary tools, in a new, crumbling reality. And in a world rapidly sliding into a prehistoric state, find out that man is not always a wolf to man, and there is always a place for friendship.
