The Make-Believe Wife (1918)

Phyllis Ashbrook hosts a party in the Adirondacks for her fiancé Roger Mason and their engaged friends, John Manning and Anita Webb. In a climbing expedition, Phyllis and John are separated from the others by a storm and seek refuge in a cabin. To save her reputation, Phyllis' parents insist that she marry John immediately, after which they may obtain a divorce and marry their respective partners. After the ceremony, John leaves for China to provide grounds for divorce, but upon discovering that he has mistakenly taken his new wife's suitcase, he returns to his apartment, where he finds Phyllis. Anita and Roger arrive and confess their devotion to each other, and when John and Phyllis realize that they, too, are in love, the divorce plans are abandoned.
