Fearless wildlife zoologist Jack Randall journeys into Australia's remote Northern Territory to encounter six dangerous pythons, including the rare Oenpelli, nicknamed "the Ghost" because only a few people have ever seen one in the wild. Along the way, Jack dives into crocodile-infested swamps, reaches into giant lizard burrows, dodges the bite of a deadly venomous snake and crawls into cramped, dark caves to find these elusive predators.

Jack travels through Australia's Northern Territory to the front line of the battle between two different species of deadly crocodiles; Jack helps scientists catch and track the dangerous dinosaurs in the hope of maintaining the balance of nature.
