Shortly before her wedding, Sasha learns that she is pregnant. She is ready to share her happiness with her lover, but instead of a wedding dress and veil she has to buy a train ticket to disappear from her hometown forever. Due to an old criminal debt, Sasha is betrayed by his fiancé. He marries the investigator's daughter to avoid going to prison. But the path to a new life for Sasha turns into a new test.

On the train, the girl meets the adventurer Valeria. A new acquaintance provoked a serious accident on the railway and fled the scene, taking a large sum of money from a nearby compartment. Sasha regains consciousness in the hospital and learns that she is being blamed for what happened and is mistaken for Lera. Later, the girl is forced to live under someone else's name and is constantly waiting to be exposed, because on the one hand she is wanted by the police, on the other – by bandits.
