Dr. Nick Harris (Thorsten Kaye) is a marine biologist hired to deal with the results of an experiment in genetics, a mutated breed of great white sharks have gotten loose on a South African shoreline whilst being transported to an aquarium.
The mutant sharks from Dr. Craven's experiments are back, this time choosing Cape Town, South Africa as their hunting ground.
When the shark kills a member of the staff and escapes, Nick and Samantha go to hunt it and discover that there are 6 mutant Great Whites living in a cave near the beach.
His cameramen Hootie (Rory Atkinson) and Pierson (Anton Vorster) warn him about the dangers of the sharks—even with the use of their protective cages.
