The Great Power

Small-town girl Mary Barry wins a beauty contest and goes to New York to meet D. V. Cortelyou, the magazine's publisher. Greatly taken by young girl, Cortelyou arranges for her to live with Dolly Griffith, a woman of questionable reputation who often aids him in his wicked schemes of blackmail and seduction.
