The offended girl refuses, and soon receives news of the death of her lover’s family - rebel soldiers plundered the count’s house and killed everyone. Later, Nadya, with the help of White Guard officers, leaves for Siberia, where in the hospital she unexpectedly meets... Alexei. But cruel fate separates them again.
