As a result of an unsuccessful experiment conducted in the laboratory of a chemical institute, a young woman gets a severe burn on her face.

Inga is a single mother. She is raising her eight-year-old son Kostya and dreams of finding him a good father. Until a certain point, all her attempts end in failure, bringing only disappointment. But then one day, she meets cardiac surgeon Andrei and falls madly in love with him. After sending the boy to the countryside for a while, Inga prepares for the wedding. Meanwhile, Andrei not only cares for his bride, but also does everything he can to rightfully call her son his own. On the wedding day, he presents his beloved with an adoption certificate. The happy newlyweds drive to the village to pick up the baby from his aunt, but get into an accident. Inga dies on the spot, and Andrei is left alone with his grief. Now he must decide the fate of the child and become—or not become—his real father.
