The Island with Bear Grylls

The men are dropped off by Bear, and they are left totally alone with the clothes they stand up in and a few basic tools. As de-hydration and hunger take hold, the men are in serious danger. If they do not find a water source and make fire, their time on The Island will be over. The battle is on as they fight for their very existence.

It's been 48 hours since the men had a meal and hunger grips the group. The race is on to bring food back to camp before they become too weak to hunt. The men take greater and greater risks in the pursuit of vital calories, desperate to seek new ways to chase, trap and outsmart the island's elusive wildlife. Ryan lashes out in anger and Craig is left deflated. And then they come face to face with one of the island's most fearsome predators - the caiman crocodile.

The men are radically losing weight. With their very survival hanging in the balance, the castaways lose patience with those they feel are not pulling their weight. Island life is taking its toll especially on the youngest castaway, 21-year-old call centre worker Ryan, who has become exhausted and isolated from the group. In harsh unforgiving heat, Ryan heads off alone in search of food.

Three weeks into their survival experience and the group is barely getting by on a meagre diet of snails and coconuts. Willing to take ever greater risks for food, Mike and Chris battle with dangerous tides, while tempers fray as it appears that not everyone is pulling their weight. Frustrated by their failure to find another caiman croc, a hunting party risks a trip to the treacherous mangroves at night.

The men enter their fourth week of living on the island, with the group hungry and divided. They elect an island leader. But will everyone back him? With island life starting to fall apart, even when a stingray arrives in the fishing nets arguments follow close behind. But as their time on the island draws to a close and a return to civilisation beckons, there are moments of redemption for some.

Bear Grylls visits the men at the end of their stay on the island to explore how they coped and how the experience has affected them. Bear also reveals the secrets of how the show was made, with a unique behind-the-scenes look at managing the medical risks and maintaining the camera kit in extreme conditions. Bear gets to see first-hand how the men have been living for the past four weeks. He tours the camp and reflects with the men on their personal approaches to surviving. When pushed to the very limit, what did they learn about themselves and each other?
