Champney Carter, a writer, late one night receives a telegram from his publishers stating that he must deliver on the following morning the manuscript of the novel he has contracted to write for them. Not one word of the story has been written yet. Putting a piece of paper in his typewriter, he begins his tale, "The Man Who Could Not Lose." Through the long hours of the night he writes with frenzied haste. The Story: Jackson Carter, an elderly man, through gambling on the races, finds himself penniless and in debt to Sol Burbank, a bookmaker, for a large amount. The bookmaker makes repeated demands for the money and at last, after a stormy interview, threatens Carter with exposure. From the shock the unfortunate man is stricken with heart failure and falls dead at Burbank's feet. Champney Carter, the gambler's son, leaves college and makes a vow to sooner or later wreak vengeance upon the man who caused his father's death.
