The action of the movie "Robinson" begins in 1985. In a small Northern town live three boys who dream of a career as Navy officers — Sashka Robertson, Leshka balunov and Vovka Titov. The submarine K-963, on which their fathers serve, goes on a secret mission — to the area of NATO exercises to find and record an acoustic portrait of the newest , almost silent American submarine. And the boys , playing submariners in an abandoned factory, fall into a deadly trap.
