In the hidden depths of Australia's wild Southern Ocean a great white shark, three meters long and packed with nearly a tonne of muscle, is savagely attacked one hundred meters below the sea's surface by a far larger and faster mystery predator...An electronic tracking device attached to the great white records a high-speed underwater chase six hundred meters deep before the shark and its tag are savagely devoured... This is the story of a super predator's epic underwater attack that leads investigators to an aquatic battle zone, never witnessed before, where killer whales, sperm whales, colossal squid and great white sharks enter into combat in an underwater colosseum where only the fiercest creatures of the marine world can survive.
