At the age of 14, Ekaterina was horrified to learn that she did not live with her own mother. She was found at 6 months old on a bench near the Orenburg railway station. The native mother left the baby and disappeared. The alleged biological relatives claim that at that time there was no child of that age in their family. But a family friend claims that there was a girl, and she personally gave her to the baby's house. Will Katya be able to find out the secret of her birth?
