When scientist Jonas Taylor goes exploring an unknown deep sea level abyss with two other scientists, he can't believe his eyes. But, after a tragic accident involving a giant called the megalodon, Jonas simply retires from his life of science and decides to teach at a university. Meanwhile, his old friend, Masao Tanaka, the person who was charge of the abyss exploration years ago, decides to meet with Jonas about an accident involving one of their own exploration machines being destroyed. With no other choice, Jonas would have to go back into the depths of hell to find out what has truly happened. Out of nowhere, the Meg shows and wreaks havoc not only Jonas, but also around others he knows and loves dearly. Can Jonas stop the Meg from killing anyone else, or will it continue to feed upon its prey once more?
