Just Sylvia (1918)

Sylvia, a model in the shop of a fashionable dressmaker, is introduced to the Hicks family, which recently has acquired a fortune through iron ore deposits discovered on their farm. Octavia Hicks sees in the cultured but unpretentious Sylvia a good match for her son Henry and invites the young woman to visit the Hicks home. Two other visitors, Frank Hayward and his accomplice Annie, are masquerading as a count and a princess in order to con the country-born millionaires out of their money. The two are introduced to Sylvia, who soon discovers their plots and exposes them. A mysterious foreign gentleman appears and announces that the fashion model is actually the Princess Sylvia of Karalyn, but she renounces her title to marry Henry.
