George Anderson (Robert Walker) is a clerk in a publishing house by day and an unpublished novelist by night. His book, called "The Mortal Sin," concerns a man whose wife sacrifices her honor to pay for his recovery from tuberculosis. In Anderson's story, the husband finds out what the wife has done and forgives her. But when the writer undergoes a similar situation in his own life, things turn out quite differently. When Anderson suffers a nervous collapse, his wife Jane (Viola Dana) goes to work for Emmet Standish, the publisher (Augustus Phillips). Standish lusts after Jane, and she only accepts his advances so that her husband can continue to recuperate out West. When Anderson returns home, he finds his wife at his boss's house and in a fury denounces, then strangles her. Anderson is on his way to the electric chair for his crime, when he is awakened -- in a desperated stretch for a happy ending, it turns out to be just a dream.
