After a brief courtship, Louise Joyce is married to her employer, architect Mortimer Grierson, who soon tires of her and begins to see other women. One night, he comes home drunk and informs Louise that the marriage was a fraud, actually only a mock ceremony arranged by Grierson's nephew Howard Hayes, then deserts her for good. Louise becomes an artist's model, and while working she meets Paul Vivian, a protégé of her husband, and the two fall in love. Grierson discovers their relationship and tells Paul that Louise was his mistress. Soon after, Grierson is mortally wounded by one of his lovers and Howard returns from Mexico to visit his uncle's deathbed. As Grierson instructs Howard to put his affairs in order, Howard confesses that Louise's marriage is legal because in an effort to spite his uncle, he secured a real minister to perform the ceremony. After Grierson's death, Paul finds Louise and learns the true story, and together they begin a new life.
