Glory and John, sweethearts since childhood on the Isle of Man, go to London, Glory to become a nurse and John to enter a monastery. Instead, Glory becomes a theater star, and John renounces his vows because he cannot forget his love for her. Lord Robert Ure, who has already betrayed Glory's friend, Polly Love, incites the London populace against John, claiming that John has predicted that the world will end on the eve of the Epsom Downs Derby. John goes to kill Glory to save her soul, but instead she convinces him of her love. Confused, John wanders into the street, is mortally hurt by an angry mob, then marries Glory before dying in her arms.
