When a government code book is stolen, an anonymous phone call discloses that the thieves are performers in a recently-arrived circus. Stanley's powers enable him to get a job with the show and befriend Teresa, one of the trapeze artists. Stanley is able to learn that the code book thieves are BoJo the Strongman and Teresa's partners, the two Flying Sylvester Brothers. Before Stanley can act on the information, the three perpetrators learn that he is a government agent and that Teresa is likely an informer. The three therefore decide to arrange "accidents" for both Stanley and Teresa.
