Every day, the heroine goes to the shore and looks at the blue surface for a long time. She is waiting for her father, a submarine captain who has disappeared, and believes that one day he will definitely return home. The other guys in her squad and the adults don't believe Lyuba, they think she's making things up and she doesn't have a father who's a submariner.
