Sumatran tiger cubs Spot and Stripe are now approaching their first birthday. They are living at Australia Zoo in Queensland under the care of their surrogate dad, British tiger expert Giles Clark. Giles must guide the brothers to adulthood in a few weeks' time and deal with the teenage rebellion that ensues. To add to Giles's responsibilities, Spot is almost blind, and Giles must help him adjust to life at the zoo. Spot and Stripe have been raising awareness about the plight of critically endangered tigers in Sumatra, and the Clark family make a big decision to safeguard the cubs' wild cousins - it's time to hit the road! Giles's wife Kerri and nine-year-old son Kynan join Giles on a road trip through Indonesia, getting up close and personal with the jungle's iconic species, from orangutans to elephants and tigers. It's a million miles away from the suburbs they're used to, but they're determined to make a difference.
