AN AQUATIC BATTLE ROYALE, WHERE PREDATORS BECOME PREY

In the hidden depths of Australia’s wild Southern Ocean, a great white shark is savagely attacked by a far larger and faster mystery predator.

An electronic tracking device attached to the great white records a high-speed underwater chase, before the shark and its tag are savagely devoured. Two weeks later, the still functioning tag is washed ashore, holding clues that could reveal the identity of the shark’s super predator.

This is the story of an epic underwater attack that leads investigators to a mysterious and powerful natural phenomenon that, for a few short weeks each year, attracts the ocean’s most fearsome predators.
