In this silent film, Daniel Boone Brown is a pleasure-seeking playboy carousing around New York City without a care in the world -- that is, until he becomes the unwitting subject of a series of experiments at the hands of a sadistic psychiatrist named Doctor Ulrich Metz . Through various means of control, the mad scientist drives Daniel to think he's losing his mind, but ultimately introduces him to the lovely Lucette .
