The story is about guys who are searching in Lake Liepaja for an airplane that sank many years ago during the war. Aivar also wants to be part of the group of guys looking for the airplane. To do this, he needs to pass a test - walk along the pier to the old fort and carve his name on the wall. On the way back, he is caught in a storm, but he passes the ordeal with honor. An old sailor Yoran, who lives on the decommissioned ship "Izabella", helps the guys in their search for the airplane.
