The Hand Invisible.

Steel magnate Rodney Graham divorces his wife, Alice, after she suffers an injury that renders her unable to give him an heir. He pursues debutante Katherine Dale, whose fiancé, Dick Allen, died on the eve of their wedding. With the help of Katherine's ambitious mother, Rodney persuades her to marry him. Katherine dies after giving birth to Rodney, Jr., and the elder Graham's stepbrother, Arthur Haynes, angrily predicts the magnate's sad demise. Rodney devotes himself to raising his son, who later falls in love with Arthur's' daughter, Ruth. Although he objects to the match, Rodney is persuaded by Alice to allow it. Upon discovering that his son was actually Dick Allen's child, Rodney plans to disinherit the boy, but is paralyzed by a stroke before he can change his will. He attends the wedding in a wheelchair and dies soon after.
