Kong. On the way to Hong Kong, an agent of the High Lama replaces the stolen Tibetan herbs with a similar bottle containing ordinary tea leaves. The Third Echelon is seeking the fuel for its own spacecraft with an underwater launching pad in Hong Kong. The goal is to be the first on the moon, where a base is to be established to launch nuclear weapons against Earth and to bring survivors under the agency's control. With a Russian launch to the moon carrying two apes imminent, the Third Echelon, which was going to emulate the Soviet achievement, decides to gain respect at the United Nations by launching two human astronauts, Chester and Harry, instead of apes. The two are used as guinea pigs (and fed with bananas) to test the capabilities of the spacecraft and the effects of spaceflight upon humans. The mission is successful, with moonlight bringing back Chester's photographic memory. Diane decides to leave the Third Echelon when she discovers that once her colleagues have extracted the final formula from Chester, they plan to dissect Chester and Harry to see the effects of space travel on their bodies. Diane helps the boys escape. They are pursued through Hong Kong, eventually leading Diane to the authorities. Chester and Harry happen to meet Dorothy Lamour at a nightclub where they are recaptured by the Third Echelon. Chester, Harry and Diane all end up in a rocket bound for another planet. They think they're alone after landing, but they're not—Chester calls out, "The Italians!" as they are joined by Frank Sinatra and Dean Martin.
