Paddy McGuinness hosts as 12 strangers begin a gruelling 18-day trek through the hostile tropical jungle of Langkawi, in Malaysia, to win a share of £300,000. But to keep the prize pot intact, they must resist the series of temptations thrown in their way. In the first episode, a custom-made swimming pool in the middle of the jungle, complete with canapés and champagne, proves too much for some to resist.

The 11 remaining fortune-seekers are split into three separate camps for 24 hours, leaving them with no clue whether the others have given in to temptation or not. Each group is tempted with a luxurious alternative to sleeping on hard wooden boards: a glamping experience, complete with midnight feast. Meanwhile, when the fortune-seekers face a leech-infested trek through murky waters, will anyone take up the offer of an air-conditioned taxi ride to their next campsite?

Each fortune-seeker is secretly offered a much-loved item from home. Meanwhile, jungle life is getting to Vicki. And will the group be persuaded by a boutique hotel with an eye-watering price tag?

The group are dealt a devastating blow and the prize fund takes a big hit. The campmates are tempted with coffee and pastries, and an all-you-can-eat Chinese buffet - but both will come at a cost.

Sealed bids to win a luxury night away from camp lead to outrageous spending. With the whole team reunited after 48 hours of being split in half, tempers flare, as each group's spending is revealed...

Will any of the group secretly steal up to £4000 from the prize pot? And they face an agonising pull on the heartstrings when they’re offered a video call with family and friends back home...

With emotions running high, a luxury spa in the middle of the jungle proves hard to resist. And the trekkers face the most lavish temptation yet: an overnight stay on a multi-million-pound superyacht!

The finish line is tantalisingly close, but the biggest bombshell yet is about to be dropped on our unsuspecting trekkers. When all the spending is done, what will remain in the final prize pot?
