Bermuda Tentacles (2014)

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?
