Siberia

Officer in the Imperial Russian Army, Petroff, is in love with Sonia, a schoolteacher who casts her lot with revolutionaries. During a time of suppression, she is exiled with her brother to Siberia. There Petroff is sent in the discharge of his official duties and secretly renews their romance. When the Bolsheviki overthrow the government, Sonia is freed and aids in the escape of Petroff, who incurs the enmity of Egor, the revolutionary leader, because he is a royalist. Together they escape across the frozen wastes in a sledge, pursued by wolves and Egor, who has used patriotism as a cloak to conceal personal ambitions.
