It's Bob Hope as phony explorer Matt Merriwether, who promotes himself as an expert on the dark continent, basing his exploration of the African subcontinent on old diaries of his uncle. When an American space capsule crashes in an uncharted region of Africa, Merriwether, based on his alleged expert knowledge of the region, is selected to recover the capsule. Joining Merriwether and his pre-Kervorkian suicide kit, is security agent Frederica Larsen (Edie Adams). Hot on their heels are Russian agents Luba (Anita Ekberg) and Dr. Ezra Mungo (Lionel Jeffries), who want to get to the space capsule first.
