In 1915 Vienna, the Austrian Secret Service recruits a widow to spy for them during World War I. Adopting the codename X-27, she gives her gifts for seduction and duplicity—as well as her musical talents—to the patriotic cause, until she finds a worthy adversary in a roguish Russian colonel who draws her into a fatal game of cat and mouse, testing the strength of her loyalties. © 1931 Universal Studios.
