On a hot summer afternoon in the sleepy town of Blackwater Louisiana, a meteor streaks across the sky and crashes through the roof of the local Natural History Museum.

Local authorities and Government Investigators join forces with Frank Abernathy, the Museum Curator, and his father Simon, a B-Movie enthusiast, to bring down the giant mammoth in this alien-invasion flick!
