Riley Elliott is a shark researcher who is determined to protect the tiger sharks off Norfolk Island, who feast on cow carcasses dumped by farmers on the old penal colony. The sharks and their behaviour have never been studied. The cow carcass dumping is about to be banned and islanders fear the sharks will come to the beaches if the cows are no longer offered. Riley and cameraman Andy Casagrande are the first to swim with the feasting sharks in an effort to find out how the sharks can be kept safe in their ecosystem and the farmers can be allowed to continue dumping the cow carcasses in the ocean.
