Kamchatka in the early seventies is an interesting place. Gold mining, hunting, proximity to 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 in with people. Lyokha Kostrov knows this firsthand. He suddenly finds himself in the body of his teenage self and is preparing to relive his past, and with luck, at least help his country a little. Lyokha is a stubborn guy, just let him turn around. He takes a big approach, learning everything from photography to shooting, mathematics to safe-cracking. And luck is on his side!
