When anarchist bombs disrupt the engagement ball of Princess Marie Pavlovna, her fiancé, Prince Michail Koloyar, helps her to escape in a carriage. Then Theo Kameneff, secretly in the pay of a foreign government, becomes dictator and, desiring the princess, issues an edict that all women between the ages of seventeen and thirty-two must register and become state property. Outraged, Marie, disguised as a shopkeeper, organizes women to refuse the order. After she is discovered by Orel Kosloff, Kameneff's henchman, Marie declines Kameneff's offer to repeal the edict if she will live with him. Kosloff then initiates mass brutality, killing women who do not register, including to Kameneff's dismay, his beloved sister, whom he tried to save. Meanwhile, Michail, who has infiltrated the Bolshevik ranks, is found out and narrowly escapes a firing squad. After he stops Kameneff's attack on Marie, Kameneff is shot by a potter, revenging his daughter's ravishment. Marie and Michail finally escape across the border.
