Massive earthquakes open the Arabian tectonic plate, resulting in unstable weather and freezing temperatures that will be unsurvivable by nightfall. Attempting to reach safety, a vacationing family in Egypt must battle the rapidly cooling temperatures that usher in a new Ice Age, covering the Sphinx, Pyramids, and Sahara Desert with mountains of snow.

When another Mega Shark returns from the depths of the sea, world militaries go on high alert. Ocean traffic grinds to a standstill as everyone lives in fear of the insatiable beast.

A pair of scientists pilot the mechanical creature as they fight Mega in a pitched battle to save the planet. But when faulty mechanics cause the Mecha to go after humans, the scientists must somehow guide Mega to Mecha in hopes that the two titans will kill each other - or risk untold worldwide destruction.
