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!

Alliances are starting to form, and as bodies ache and morale drops, the temptations are becoming harder to resist.

Fatigue is setting in and the mood in the group is at an all-time low. They could do with a pick-me-up - just like a lavish party that's plonked right in their path...

Twelve Brits land in South Africa to begin a gruelling 18-day trek. Will they spend any of their prize pot along the way? When a single shower costs £1000, the bill can rack up quickly...

A vast ideological split has formed between the trekkers. Will any of them trade a chunk of the prize money for an evening in a living room that's just like home?

The prize fund has taken some hits and the trekkers are divided. But will that stop anyone from spending more of it on a trip to a cocktail bar?

The trekkers enter the final stretch of their journey, and the prize money is tantalisingly close. But a bombshell rule change throws everything up in the air.

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...

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?
