As a result of an arctic nuclear test, a carnivorous dinosaur thaws out and starts making its way down the east coast of North America. Professor Tom Nesbitt, only witness to the beast's existence, is not believed, even when he identifies it as a "rhedosaurus" to paleontologist Thurgood Elson. All doubts disappear, however, when Elson is swallowed whole during an oceanic bathysphere excursion to search for the creature. Soon thereafter the rhedosaurus emerges from the sea and lays waste to Manhattan Island until Nesbitt comes up with a plan to try to stop the seemingly indestructible beast.

When an undersea volcano sends tremors throughout the Atlantic, aquatic creatures come out of hiding. Merchant seamen Joe Ryan and partner Sam Slade harness the most unusual of the lot, a massive beast that looks like a Tyrannosaurus Rex. The enterprising sailors deliver their quarry to a British circus, but it turns out that the animal is a newborn. And, when his much larger mother arrives in London to rescue her son, the city feels her wrath.
