When Air Force One goes down over the Bermuda Triangle, the Navy sends its best rescue team. But in saving the president, the team awakens a monster which threatens America's entire Eastern Seaboard and, ultimately, the world.

A violent tempest and a set of lightning flashes above the infamous Bermuda Triangle takes out one of Air Force One's engines, and President DeSteno narrowly escapes in his pod. As Chief Trip Oliver and Admiral Linda Hansen's Special Forces team comb the ocean to locate the president before he runs out of oxygen, monstrous tentacles emerge from the bottom of the sea, attacking the ships and everything in sight. Now, modern weapons are completely ineffective against the gigantic adversary, and the clock is ticking. Can they stop the beast from the sea?
