The Divine Sacrifice (1918)

Dr. David Carewe's already unhappy marriage is made worse when his wife Helen's refuses to have children. Helen poses as the wife of gambler Robert Spencer in Europe, while David falls in love with Spencer's wife Madeline. When news reaches David that Spencer and his supposed wife have been killed, he weds Madeline and they have a daughter, June. Helen suddenly reappears, but David renounces her and continues to live happily with Madeline. Eighteen years later, June falls in love with a young man who is revealed as the son of Spencer and a woman to whom he was married before Madeline. Rather than ruin the budding romance, Madeline asks Helen to pose as June's mother, which restores June's name and allows the young lovers to marry.
