Piękna nieznajoma (1993)

Strangers on a train. Late in 1916, a brave and idealistic Russian officer in his 20s comes to his superiors' attention when he stands up to Rasputin at a nightclub. He's asked to carry important papers from Petersburg to Stockholm by train in the dead of winter, a dangerous mission. The first-class carriage may be full of spies, and soon after the train embarks, the man in the next compartment searches Obozow's luggage. A beautiful stranger approaches him, a woman older than he, on a concert tour; a game of cat and mouse ensues with patriotism and emotion sometimes on opposite sides. Can Obozow consummate the affair, reach Stockholm, and maintain his ideals?
