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.
