Summer, 1943. A group of secret service men of an artillery division runs against a 12-year old boy during the raid upon the enemy troops. The boy looks absolutely stunning dirty, ragged, angry and hungry a real wolf cub. They take him and find out that the boys name is Vania, and hes been wandering about woods near 2 years, eating whatever he finds and hiding all the time. The command makes a decision to send the boy to the rear, but he refuses. Finally the boy gets permission to stay and helps the scouts in their work.
