Dean, a spy, is shot by the Wolf, an international crook, just as Marguerite is passing the lonely spot in her auto, so the heiress takes the wounded man to her home. Before he dies the spy turns over to Marguerite a bracelet containing papers concerning the invasion of America and a code book. Later the Wolf steals the bracelet and when he is followed by Fred, Marguerite's friend, he leads him to his den. Before turning Fred loose he seeks to terrorize him by signs of his astounding power. A later raid on his lair headed by Fred is unsuccessful. Meanwhile the Wolf has discovered that the bracelet is valueless without the code-book and we are left to surmise his attempts to secure that in the next episode.
