A codebook has been stolen from the Office of the Defense Department. An anonymous call says someone in De Witt's Traveling Circus is involved. The Office of Secret Projects summons Stanley to get a job at the circus and investigate where the codebook is hidden. Guarding against his usual exit crashing through the office window, a ramp has been installed. The circus hires Stanley as a strongman, to the anger of resident strongman Bojo (Ted Cassidy, Lurch from "The Addams Family"). Stanley is helped by Teresa (Susanne Cramer), a member of the Flying Sylvesters, who cautions him to be careful from bad people in the circus. She is also the one who phoned the government about the codebook being there and further states her two partners and possibly Bojo is involved in the theft. Tiny (Frank Delfino) overhears Stanley relaying the information by phone to Mr. Reed and alerts Bojo and Adam (Carmelo Manto) and Nigel Sylvester (Peter Tenen). The Sylvesters plan an accident for Teresa while Bojo prepares the gorilla Condu to dispatch of Stanley.
