My Wife (1918)

To prevent her niece from becoming an old maid, Beatrice Hammond's aunt stipulates in her will that the girl must be married by the age of eighteen or sacrifice a million dollar inheritance. Beatrice is in love with Ronald Farwell, but he has been called to fight against the Germans in France, so Beatrice approaches her guardian, Gerald Eversleigh, with a plan: Gerald will marry her, thus insuring that she will inherit the fortune, but divorce her as soon as Ronald returns. The wedding is staged, and all goes well until Gerald falls in love with his wife. Meanwhile, Ronald falls in love with a French nurse and, upon his return home, offers to pay Gerald to remain married to Beatrice. Gerald happily accepts the offer but refuses the money, and Beatrice discovers that she has loved her husband all along.
