Bear Grylls abandons 14 women on a desert island in the Pacific. As night falls on Day 1, they make camp in the jungle - at the mercy of deadly creatures and voracious sand flies.

The men have barely slept or had a real meal since landing. And a bitter rivalry between the island's two builders, Paul and Andy, has turned into all-out war.

The camp has split in two and is dangerously low on water. As the main group head into the jungle, looking for lost members, they're in for a nasty surprise.

The men come face to face with a fearsome predator; The group's body weight and energy levels plummet, there's division and conflict in the camp.

Starving and seriously dehydrated, the group leave camp looking for water. They find two pigs, but can't agree whether to adopt them, or eat them.

The men build a raft to go fishing. But, as Vic gets dragged towards razor-sharp rocks, he faces a life and death struggle to turn the raft around.

The extreme conditions are taking their toll, with the women on the brink of starvation. Lauren, Beth and Belinda go pig hunting in the jungle.

It's almost four weeks into the experiment and the women are entering dangerous medical territory. They're given a 36-hour deadline to turn things around.

Hunger and disorganisation is causing the group to fragment. Lauren and Beth make a push for leadership but Jaime and Belinda push back.

After five weeks on the island, the men are low on food and energy. They make a last bid to hunt for food before Bear arrives to take them back to civilization.

Bear meets the men and women who made it through six weeks on a Pacific island, to see how they coped battling hunger, thirst, and each other, in one of the biggest tests of their lives.
