Half a Rogue: When New York playwright Richard Warrington returns to his home town, Republican bosses nominate him for mayor. The Democrats, alarmed at Richard's popularity, decide to unearth a scandal that will ruin his chances of winning and quickly discover that, months before, actress Katherine Challoner had spent the night in Richard's apartment. Although it simply had been the result of Katherine's fainting spell, the home-town Democratic newspaper turns the overnight visit into an illicit rendezvous between two lovers.
