On a hot summer afternoon in the sleepy town of Blackwater, Louisiana locals exiting a retro-fitted theater excitedly watch as a meteor streaks across the sky and crashes through the roof of the local Natural History Museum. No one realizes that the meteor is actually a spaceship containing a shape-shifting life form. In order to adapt to Earth's atmosphere, the life form latches on to the first organism it comes in contact with - a partially frozen Woolly Mammoth found in the historic exhibit for which the town is famous.
