Smitten by Diana's beauty and kindness, David swears off the bottle, as he nurses her back to health. He returns to London, where he rises to prominence once again. Here he crosses paths with his beloved Diana, and is shocked to find her married to wealthy Gordon St. Claire, a notorious womanizer. Gordon humiliates his wife on a daily basis, even forcing her to entertain his lovers at their home. When he is poisoned, Diana is arrested and charged with murder. As scandalous headlines fill the newspapers, David works desperately, to try to prove the innocence of the woman he loves.
