In the Crimea, on the shore of the Black Sea lives a girl nicknamed Dubravka. The girl plays soccer, swims in the sea, runs with boys in a race and often becomes a participant of any adventure. But the time comes - and Dubravka begins to grow up. She is as if in a “suspended” state: she is no longer interested in playing with boys, and older boys and girls do not pay much attention to her or perceive her as a child. In the house Dubravka settles vacationer Valentina Grigorievna. The girl likes her so much that Dubravka even “fell in love” with her. Dubravka's neighbor, the lonely father Peter Petrovich, and Valentina sympathize with each other, and Dubravka becomes very jealous of her. The girl does not know where to go from the contradictions simmering in her.

A telefilm about how a common cause and a dream helped classmates living by the sea find friendship...

Eight-grader Petya Kopeikin, despite his short stature and nondescript appearance, is constantly in the spotlight. Petya is noble, witty, well versed in literature, he writes wonderful poems. Kopeikin has long been secretly in love with his classmate Masha Goroshkina, and she is passionate about the new student from 9 "A" Kolya Kristallov. Masha tells Petya about her feelings and asks him to hand over a note to Kolya. Deeply worried from unrequited love, Petya not only doesn't stand in the way of a happier rival, but even helps him win Masha's heart. He wants to prove that courage and honor were not only inherent in the times of “musketeer” novels, but exist in our time. Petya chooses to follow the example of the hero of the famous play Edmond Rostan and in his actions copies Cyrano de Bergerac.
