 The mutant sharks from Dr. Craven s experiments in "Shark Attack 1" are back, this time choosing Cape Town, South Africa as their hunting ground. Two sisters, Amy and Samantha, while diving near a wreck in the reef are attacked by a shark; Samantha survives. One week later, Dr. Nick Harris and his assistant get the shark and install it as a new attraction at Water World - a Sea World rip-off. When the shark escapes, Nick and Samantha go to hunt it and discover that there are 6 mutant Great Whites living in a cave near the beach, and the Water World s surfing competition might be the next victim! Now they team up with Roy - a Discovery Channel shark hunter - to kill the beasts and save Cape Town.
