Harry Larrabee, a young playwright, lives in the same studio apartment house with Carolyn Vaughn, a painter of miniatures, with whom he falls in love. "The Wolf," a famous criminal, supposed to be dead, returns and communicates with his wife, a friend of Carolyn's. He forces his wife and her brother to aid him in a plot to rob Carolyn of her valuable jewels. Harry, by one of his famous "inspirations," discovers that a crime is being committed, rescues Carolyn and bears her away in a taxicab. He is himself suspected of the crime, but, undisturbed by the web of circumstance by which he is entangled, his wonderful inspirations give him the key to the conspiracy which led up to the crime. In an unusual and powerful finale the guilty parties fight among themselves and justice triumphs in an exciting climax.
