Oil... the quest for it is unrelenting. The search for new reserves of the �black gold' never-ending and leading the search Nexecon Petroleum and its flagship, the largest drilling refining platform ever constructed, �Colossus' located in the freezing North Atlantic waters off the coat of Iceland.

�Colossus' will drill deeper than any rig ever has, a fact that has geologists the world over up in arms, concerned that the delicate ocean floor fault lines could be disturbed with catastrophic effects.

They are soon proved correct, but in a way no-one could ever have imagined...

News Reporter �Christen Giddings' and her Camera man has been invited by the CEO of Nexecon �Peter Brazier', to report on the grand opening of the rig. Colossus tears through the seabed striking a rich oil deposit. As the drill penetrates further it ruptures a fissure that reveals a second �mirror' ocean that has existed beneath ours for millions of years. An ocean teaming with prehistoric life. As the choking oil poisons the water, the frenzied creatures swarm for the surface. Colossus buckles under the onslaught. Brazier, Christen and a team of engineers, decend to assess the damage, and come face to face with the most powerful oceanic predator that ever lived, Carcharadon Megalodon. The giant ancestor of the Great White shark.

This eleven-ton �killing machine' quickly stakes its territory in the waters surrounding colossus with disastrous and horrific consequences, destroying and devouring anything in it's path.

Now fate will pull them together as they wager their chances of survival against the most fearsome creature that ever dominated the ocean. And pit the technology and machinery of man against beast.
