In Siberia, an archeological expedition searching for prehistoric fossils discover a large prehistoric monster, perfectly preserved in a state of suspended animation in the ice. It's as lifelike as it was millions of years ago when it roamed the earth in the Mesozoic age. The tireless workers of the expedition eventually find a way to remove the large monster from the ice, and they load him onto a special Refrigeration freighter, and transport him to North America, to the city of Metropolis, USA. Here, Alfred R. Ley donated this monster to be displayed at the Museum of Natural Science, where it is being held in a special refrigeration device.

Trapped on a remote island by a hurricane, a group discover a doctor has been experimenting on creating half sized humans. Unfortunately, his experiments have also created giant shrews, who when they have run out of small animals to eat, turn on the humans.
