Meg

A deep-sea submersible with an international research crew lies incapacitated on the floor of the Pacific after being attacked by a massive shark previously thought to be extinct. Experienced deep-sea rescue diver Jonas Taylor is recruited by a visionary Chinese oceanographer to save the crew and the ocean itself from this unstoppable threat: a prehistoric 23-meter-long shark named Megalodon. What no one could have imagined is that Taylor had encountered this terrifying creature years ago. Now he must risk his own life to save everyone trapped below and face the greatest predator of all time once again.
