Mother Eternal(1921)

Unable to support her second child, a boy, Alice Baldwin gives him up to the wife of Edward Stevens, a wealthy manufacturer. Her other child, a daughter, grows up, marries, and selfishly neglects her mother. Twenty years pass, and Alice's son, Edward, Jr., wins a place in the Stevens piano factory and falls in love with Julia Brennon, the owner's daughter. Meanwhile, the mother leaves home when her son-in-law objects to her presence, and she is rescued from a suicide attempt by Edward and Julia. At his foster father's home he realizes her identity, and at last they find happiness together.
