Having married businessman Dorokhin, orphan Darya Kravtsova faces constant abuse from her husband. The only thing that keeps Darya in the family is her stepson, little Kostik. But Dorokhin's entire business is built on the inheritance that Kostik received after the tragic death of his mother and grandfather. Dorokhin is rude to Dasha, who did not live up to his expectations, and is angry with the boy on whom he is completely financially dependent. One day, Dasha and Kostik get into an accident. The car sank. Dasha and Kostik are presumed dead. But this is not so. Dasha decides to take advantage of the situation and run away, since it is not safe to stay in Dorokhin's house. On the advice of a friend, Darya and Kostik flee to the city of Kalanchevsk, where her mother lives, with whom she had not communicated before.
