On a naval expedition to Antarctica, three men and reporter Maggie Hathaway crash-land in a crater 1000 m below sea level. There, they encounter steamy tropical forest, dinosaurs, carnivorous plants, and human footprints, as Maggie’s clothes become more and more abbreviated. Soon they stumble upon the lonely Dr. Carl Hunter, lost in another expedition twelve years ago. He offers a way out to the three military provided they leave Maggie with him. What will they do? Starring Jock Mahoney, Shirley Patterson, and William Reynolds. This story was allegedly inspired by the discovery, in 1947, of an area of inexplicably warm water in Antarctica. The Tyrannosaurus head from this movie was reportedly used to create Spot under the stairs of the Munster House on The Munsters television show (1964).
