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. 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.

O jovem Daniel Brown cai nas garras do doutor Ulrich Metz, um psiquiatra que tenta hipnotizar o rapaz e levá-lo ao suicídio. Agora, Daniel precisa lidar com as engenhosas artimanhas do médico para se salvar.
