Un capitán de cosacos

In Russia in 1910, Captain Sergio Danikoff is exiled to Komsk, Siberia because of his affair with a woman. When the train on which he is riding makes a stop, Tanya Trainoff, a young woman, joins a nervous-looking man, Ivan, who is her brother. Ivan and the men traveling with him convince Tanya to help them in their scheme to get a twenty-thousand ruble ransom in exchange for the woman they are about to kidnap. Feigning weakness, Tanya keeps Sergio busy while the men kidnap Olga Nicolaievna, the mistress of General Fedor Petrovich, the governor of Siberia. When the train arrives in Komsk, Ivan reports the kidnapping to Petrovich, who is outraged. Sergio begins to search for Olga, and his search leads him to Tanya's house, where a barking dog gives away Ivan's hideout in the adjacent barn. Olga is recovered, and several days later at Petrovich's mansion, when Olga leaves the festivities early because of a headache, Sergio's old friend, Nicky Baglieff, suspects that Sergio has been flirting with Olga and assumes that the headache is a ruse. In order to keep Sergio and Olga from acting on their flirtations, Nicky challenges Petrovich and Sergio to a game of chess. Petrovich and Nicky both become suspicious when they arrive in Sergio's room to see him preparing for a romantic evening. After calling Olga's room to ensure that she has not sneaked out to rendezvous with Sergio, the two men leave Sergio. He is soon joined by Tanya, who confesses that she helped Ivan with the kidnapping and asks Sergio to help free her brother as well as her ill-treated fellow citizens. The following day, Sergio convinces Petrovich to free Ivan and the other prisoners so that Petrovich's men may follow them and investigate what they are truly up to. Petrovich agrees and he holds a festival to celebrate. At the festival, Tanya is attacked by the drunken Petrovich. Hearing her struggle, Ivan comes to her rescue, and they are chased from the celebration by Petrovich's guards. Sergio joins the search for the fugitives, and spotting Tanya in the woods, he leaves the search party in order to reach her without the others' knowledge. As he comes upon her, Tanya's horse throws her, knocking her unconscious. He takes her to a nearby cabin and, after ensuring that she will be okay, rejoins the searchers. At Petrovich's mansion, Sergio is confronted by the governor, who has plans to hang the captured prisoners. Petrovich has the prisoners brought in, and Sergio is shocked to see Tanya among them. Having found out what Sergio did for Tanya, Petrovich has Sergio arrested as well. After a period of initial suspiciousness, the other prisoners join Sergio in a revolt. Armed with a gun, Sergio tells Petrovich that his men have overpowered the guards, and then Nicky, who is in on the plan as well, reads a fake telegram that instructs Sergio to proceed with Petrovich's arrest and removal to St. Petersburg. Petrovich becomes alarmed and asks Sergio to take pity on him because he has less than one year to live. Sergio agrees, and as Petrovich and Olga leave to the taunts of the crowd, he sings a love song to Tanya.
