The remote islands off the Eyre Peninsula in South Australia are believed to harbor some of the biggest white sharks on the planet. While local fishing reports suggest these giant sharks are still around, they are rarely seen.

One of last year's most popular Shark Week shows returns. Marine biologist Dr. Austin Gallagher, marine scientist Liv Dixon, and legendary cameraman Kina Scollay travel to a new location and head back into the belly of a 29-foot whale decoy with new shark attractant features to create the biggest feeding frenzy ever with 18-foot 'Breeder' sharks in New Zealand.

Orcas and other toothed whales are attacking Great Whites in record numbers, marking the latest chapter in a 60-million-year battle between Sharks and Whales. This rivalry began with The Leviathan, a prehistoric whale that once went tooth to tooth with the greatest predator to ever swim the oceans... The Meg. Now, Dr. Tristan Guttridge, Dr. Sona Kim, and Kina Scollay recreate these epic battles and study orca tactics to discover the ultimate predator.
