The six inexperienced backpackers from disparate social backgrounds are dropped in a back street of Jakarta, Indonesia.
The tension mounts among the girls, while the boys are seeking some adventure as the six inexperienced backpackers are put to the ultimate test with a set of challenges in Indonesia to win £10,000 and the title of Ultimate Traveller.
The inexperienced backpackers face their toughest challenge yet, navigating their way to the island of Bali, a 400 mile journey without the help of guide books or maps.
The next challenge for the backpackers is to make as many new friends as possible. Sounds easy, but then they'll have to persuade their new pals to drop everything and join them on the island.
The backpackers make their way to Lombok. Taking on the challenge of working in traditional local industry, the travellers taste the real demands of island life and allegiances fade.
Still in pursuit of the prize, the latest travel challenge sees the contestants go native - spending two nights living in the traditional Indonesian villages on the island of Sumbawa.
With only one week to go, the travellers make their way to Flores, the next island east where both groups must complete the challenge of two full days on their own voluntary project.
It's the final week of the trip and the group are put to the ultimate test with a set of challenges in Indonesia. Out of the six backpackers only one can be crowned 'Ultimate Traveller' and win the coveted £10,000 cash prize.
