A Midnight Romance(1919)

Marie, a hotel maid, falls in love with millionaire's son Roger, but Roger cannot marry her because of her inferior station and his unwillingness to make his family unhappy thereby. They separate. When next they meet, Roger discovers that Marie is actually a princess. Now their renewed romance cannot continue because Roger is a mere commoner. But the Bolshevik revolution provides complication and at last resolution to their dilemma.
