Wildlife zoologist Jack Randall journeys deep into the Australian outback to fulfill his lifelong dream of being accepted into a "mob" of wild kangaroos. Along the way, Jack snatches up snakes, lunges after lizards, defends against dangerous dingoes and even rescues an orphaned baby kangaroo in the hopes of teaching it to fend for itself before being released back into the wild.

Zoologist Jack Randall explores Australia's remote Cape York peninsula to confront five of the most venomous snakes in the world, including the elusive Coastal Taipan. Along the way, Jack encounters huge pythons and terrifying tarantulas and joins forces with a local wildlife legend to determine which is the deadliest snake "down under."
