Together with other graduates of the Maritime Institute, Irina Zakharova returns to her native Odessa. At the distribution commission, she seeks the appointment of the first assistant to the captain on the infamous Pobeda vessel, with the most loosened crew. Carrying a personal example of sailors, Irina successfully fights for a turning point in the mood of sailors, and when the ship gets into a storm, she shows the outstanding qualities of a real sailor. Against the background of these events, the theme of lyrical relationships between Irina and the navigator of the red-flagged ship "Abkhazia" Vasily in love with her is unfolding.
