Author George Clayton (H.B. Warner) is a skeptic when it comes to hypnotism. Nevertheless, he allows mesmerist Norman Osgood to put him under. The next day, Harrison Kirke (Howard Davies) is found murdered, and Clayton is the prime suspect because Osgood -- who had a grudge against the victim -- supposedly commanded him to do the deed "one hour before dawn." Only through the skilled work of Inspector Steele (Wilton Taylor) is Clayton found innocent of the crime. This mystery story received fine direction at the hands of Henry King, who was beginning to make quite a name for himself. It was based on Mansfield Scott's novel, Behind Red Curtains.
