Also joining them is Matt's sister (who is Luke's ex-girlfriend) Kate (Zoe Naylor) and fellow sailor Warren (Kieran Darcy-Smith). To get to Indonesia, they must sail through a coral reef.

Off the coast of Alaska, oceanographer Emma MacNeil (Deborah Gibson) is studying the migration patterns of whales aboard an experimental submarine she took without permission from her employer. Meanwhile, a military helicopter drops experimental sonar transmitters into the water, causing a pod of whales to go out of control and start ramming a nearby glacier. In the chaos, the helicopter crashes into the glacier, and the combined damage breaks the glacier open, thawing two hibernating, prehistoric creatures. MacNeil narrowly avoids destruction as, unknown to her, a giant shark and octopus are freed. Some time later, a drilling platform off the coast of Japan is attacked by the octopus, which has tentacles large enough to wrap around the entire structure. After returning to Point Dume, California, MacNeil investigates the corpse of a beached whale covered with many bloody wounds. Her employer Dick Richie (Mark Hengst) believes them to be from a tanker propeller, but MacNeil insists they appear to be from a creature. Later, she extracts what appears to be a shark’s tooth from one of the wounds. Elsewhere, the huge shark leaps tens of thousands of feet into the air from the ocean and attacks a commercial aircraft, forcing it to crash into the water.

The film begins with a group of divers installing a power cable at the bottom of the Pacific Ocean, when a shark swims up and kills one of them. Six months later, lifeguard Ben Carpenter (from the first Shark Attack film) and his partner Esai drive out to sea to catch some lobster. While diving, Ben finds a broken power cable with a large shark tooth stuck in it. After he pulls out the tooth, he is caught by two other divers, and soon goes back to land. Later he posts a description of the tooth online, but as he cannot find a matching shark tooth on the internet, he names it "mystery shark". Natural history researcher named Cataline "Cat" Stone gets the message, finds him and looks at the tooth. She believes it to come from a huge prehistoric shark called Megalodon (Greek for "big tooth").
Depuis l'enfance, Rob Stewart se passionne pour les requins. À tel point qu'il est devenu biologiste et photographe sous-marin afin de pouvoir nager avec eux, décrypter leur mystère et déconstruire le mythe du requin mangeur d'hommes. Ce mythe, entièrement fabriqué, serait selon lui responsable de l'indifférence qui entoure, un peu partout dans le monde, le massacre de la population de requins à des fins commerciales. Du Costa Rica aux Îles Galapagos en passant par le Guatemala, Stewart et l'équipage de l'activiste des mers Paul Watson tentent de dénoncer et de mettre en échec les braconniers à la solde de mafias asiatiques soutenues par des gouvernements corrompus. Il y va de l'équilibre écologique de la planète.
