A video surfaces purporting to document a megalodon attacking an adult sperm whale. Treasure hunter and soldier of fortune, Enzo Palmer, becomes obsessed with proving it’s real. With his voluptuous inamorata, skeptical partner and his somewhat harebrained paramour, Enzo embarks on an around the world monster quest. From Key West to the Sea of Cortéz the team dives, trolls and trawls in their high stakes voyage to prove the gigantic living fossil still lurks in the depths. However, there is competition on the horizon in the form of a slightly deranged megalodon enthusiast who has the support of environmental activists with malevolent intent.
