Researchers investigate if orcas are hunting great whites in New Zealand.

Dr. Riley Elliott returns to Norfolk Island with underwater cinematographer Kina Scollay to see what happens when the island's tiger sharks go head-to-head with migrating great whites over an unusual food source: cow carcasses.

Kina Scollay and his team return with a one-person submersible to a top secret location attempting to locate a great white shark mating ground.

Scientists set out to learn how great whites defeated a super-predator.
