Eleven Aussie celebs are paired up with their nearest and dearest in a thrilling, globe-trotting race to win money for charity. First stop: the busy streets of New Delhi.

The race continues in Cambodia, where a spiritual journey leads the teams into the world's largest religious monument, Angkor Wat, on a search for enlightenment with a real-life monk.

The celebrity duos navigate the waters of an incredible floating village on the mighty Tonlé Sap Lake. At its Chong Kneas school, children teach them a song in the Khmer language. Then the teams must either farm or fish for local food staples.

Our teams clown around at the circus in Cambodia's second-largest city, Siem Reap. A fiddly floral task brings mud, sweat and tears. And one pair have a meltdown.

In Kerala, the teams tackle tiger stripes, stick strikes and tuk-tuks, before tucking into a bounty of bananas! But a careless mistake could cost one duo dearly.

In India's city of love, Agra, the racers battle exhaustion, extreme heat and even a monsoon. But will learning a Bollywood dance be a step too far? And who'll be sent packing?
