Soobrazitelny’s crew is having a final rehearsal before the parade. While docked at the civilian port, they are allowed to give guided tours on board the ship. Lieutenant Karakash is tasked with conducting them to redeem his other shortcomings at work. At the same time, a sailor aboard the Magnitogorsk submarine celebrates his birthday 40 meters below sea level. Later in the day, the crews of both vessels receive well-deserved accolades.
