An exploratory dive into the deepest depths of the ocean of a daring research team spirals into chaos when a malevolent mining operation threatens their mission and forces them into a high-stakes battle for survival.
A deep-sea submersible, part of an international undersea observation program, has been attacked by a massive creature, previously thought to be extinct, and now lies disabled at the bottom of the deepest trench in the Pacific with its crew trapped inside. With time running out, expert deep sea rescue diver Jonas Taylor is recruited by a Chinese oceanographer to save the crew – and the ocean itself – from this unstoppable threat: a pre-historic 75-foot-long shark known as the Megalodon.
