Madeline Jekyll meets Baron Stana, a distinguished looking man, and finds her father has promised her in marriage to Daggerts, a politician, who, in reward, has agreed to see that Jekyll is elected governor. Madeline is already in love with Robert Mayhew, and rebels at the prearranged marriage. Later Madeline overhears Baron Stana and Daggerts threatening to expose Jekyll because he has forged Daggerts' name to a note, unless he gives his daughter's hand to Daggerts. To save her father she stops Daggerts with the demand, "What is your price?" He replies, "You," and she agrees to marry him in return for which he hands over to her the incriminating note. When Jekyll learns of his daughter's sacrifice he is almost crazed with grief, and that night dies of a broken heart. Madeline, in her boudoir, dreams that Stana appears before her. He tells her that Daggerts loves her for her purity and innocence and to escape him, she must become the antithesis of this: hard, sophisticated and reckless. Stana then takes her to a luxurious dance saloon. Horace, a young gentleman of leisure, falls in love with her, but meets only ruin and death, while she and Stana continue on their way until, finally, Madeline sees herself old, dissipated and forlorn. Then Stana taunts her and she kills him. Awakening from her dream Madeline learns of her father's death. Daggerts and Stana quarrel and the former is frightened to discover that bullets have no effect on the Baron, who, with a sardonic laugh says, "I am Satan, and you are mine." Daggerts drops dead from heart failure, leaving Madeline and Mayhew to their complete love and happiness.
