On the day of a family celebration, Sonya Melnikova’s life is turned upside down: she learns that she was adopted. Many years ago, her parents found a little girl in an abandoned district of Nerechinsk and, without informing the authorities, took her away.
Stunned by this discovery, Sonya goes to Nerechinsk in hopes of finding her roots. It is there that her path crosses with Oleg’s, the adopted son of a Moscow businessman, who has long been trying to uncover the mystery of his real parents’ deaths.
Although Sonya manages to find her biological mother, burdened with caring for her new family, she rejects her. Having lost her last hope, Sonya is about to leave, but Oleg convinces her to stay and help with his investigation. Little do they know that the search for the truth about the past is inexorably leading them to one shared secret.
