The action takes place today in a big city.

Room in the style of the fifties. Valentina’s grandmother is in the chair, Valina’s mother is near, and Zhenya, the elder sister, is at the mirror. Waiting for Valya. Mother is outraged. It seems to her that Valya is too loose: in the subway she walked in an embrace with a young man. Mother thinks that Valya will leave the institute, cripple her life, starve, produce beggars. Eugene is trying to explain to her that nothing terrible is happening, that everyone is walking like that now, but her mother does not want to listen to anything.

Valentine is coming home. Mother immediately begins to report to her. She says that she rolls on an inclined plane, that she has no shame, that due to a stupid mistake, she can break her life, that she takes for love something completely different, that at the age of eighteen the “boy” has no right to marry. Valya says that his mother treats him like that because his mother is a conductor, and she will not choose - profitably, disadvantageously. They have three rooms, can there really be no room for him? But the mother screams so that they do not hope that there is nothing to creep into their living space, asks Valya to remember that she does not have anything, and while she lives with them, she must do as they want. She forbids Vale to even see the boy. Valya runs away.

Valentine's apartment. His mother, Lisa, is also not enthusiastic about his intention to marry. She has nothing against Vali herself and against their meetings, but she believes that it is too early for her son to marry. They live too hard, and starting at his age from scratch is even harder. They will have nowhere to live, nothing to eat. Lisa is afraid that Valentina will not live with them in difficulties, and her family will never accept her son. However, she leaves the freedom of choice to her son. Valentine escorts his mother on a flight, promising to take care of her sisters. Katya, a neighbor, comes to him. Katya is in love with him. Lisa believes that she is the best couple for Valentine than Valya, because Katya is from their midst. But the son of a different opinion. Katya leaves for the village, and Valentin asks her to leave him the keys.

Valentine comes. At first they only say that about their feelings. Then Valya asks how they will live. Valentine says that he will transfer to correspondence, go to work. After all, people even died for love! Valya suffers from the fact that she has to constantly deceive everyone, that she is not understood. Valentine is afraid that she will not stand, will break.

Valentine's friends. They learn about the whole situation and decide to raise money to help them so that there is a place to start. They also want to rent a room for young people. At this time, Vali's sister, Zhenya, takes her to a party with her. There, Valya meets a young naval officer Alexander Gusev. He is single and is looking for a girlfriend of life, since in the material sense everything is going smoothly for him. He offers Vale to marry him, but she says that she loves another.

A week goes by. Katie’s room. All week, Valya slowly took things away from the house and hid them here. Yesterday she decided on everything, did not go home, sent a friend there to say that she would not come to sleep. Valentine told everything to his mother, she took the key and arranged everything, said she would not leave them. Valya unexpectedly tells Valentin that she didn’t send her friend anywhere, she didn’t say anything to her parents: she lied that she was preparing to be offset by another friend. She is ashamed that she wakes up in a strange house, that she has become different, that her parents are probably already looking for her.

Lisa tells her friend and friend, who drink in her kitchen, about her son. Rita and Volodya support her. Volodya even wants to help with young money. Suddenly Eugene and Valentina's mother come. Lisa apologizes for friends, and Valentina's mother is horrified that her daughter goes to such a place, Zhenya apologizes for her mother. Valentina’s mother believes that it is too early for their children to marry, that they need to be divorced, not allowed to go to each other. Lisa disagrees with her. In her opinion, it is better to support children so as not to cripple their souls. Lisa is sorry for Valentine even more than her son. Enter Valentine and Valentine. Mother slaps Valentina and says that her grandmother dies because of her. Valya cannot but go with them. Lisa wants Valentin to catch up with them, but he refuses.

Valentine comes to friends who have already raised money for them, rented a room. Valentine reports that all their efforts are in vain.

Valentina is at home, lying in bed, she has fever, chills, trembling. She doesn’t want to see anyone. Mother deceived her: grandmother did not even think of dying. It was only an excuse for Valya to return home. Valais say that everything is done only for her happiness. Valya jumps out of bed and wants to go to Valentin. Mother forbids her to leave home. Zhenya stands up for Valya. He says that her life has already been broken, she will not let Valin break. Mother surrenders, opens the door, says that she is tired and that she can no longer. Valya does not leave: she cannot “finish off” her mother.

Valentine is returning home. Volodya tells him that he must fight for his love, that he must go to Valia, marry her, and Volodya will help with work and housing. Valentine and his friend are trying to call Val from the street, but her phone does not answer. A passerby tells the guys about love. He says that love is when nothing is ashamed, nothing is scary. When they wait and believe that a person will come anyway. The guys are stunned. Valentine wants to be alone.

Valentine appears ... They won the first victory.
