James Rallston, facing financial hardship, marries a wealthy invalid widow with a daughter, Jean, and plots to control her fortune. He orchestrates her confinement in a sanitarium by drugging her and falsely claiming she is insane, with the help of a conniving doctor and sanitarium keeper. Fifteen years later, Rallston has lost Jean's fortune through speculation and seeks help from John Bigelow to recover it, offering Jean as a reward. Bigelow, suspicious of Rallston, discovers the truth about the widow and Jean's father, and rescues the widow from the sanitarium.
