Kamchatka in the early seventies is an interesting place. Gold mining, hunting, proximity of the border, life in harsh northern places and Far Eastern characters. It's easy to find a friend here, but it's hard to get out into people. Lyokha Kostrov knows this firsthand. He suddenly finds himself in the body of a teenage himself and prepares to relive his past, and with luck at least a little help to his country. Lyokha is a stubborn guy, just let him turn around. He approaches the matter on a large scale, learning everything from photography to shooting, from mathematics to hacking safes. And luck is on his side!
