Treasure Island with Bear Grylls

In just the clothes on their back, with a day's supply of water and a few basic tools, the group is abandoned on the treacherous south east side of the island. They are immediately confronted with their first big decision when a helicopter flies overhead and parachutes a box of cash on the north shore. Do they chase the money or try to make camp? Bear keeps a watchful eye on proceedings.

Four days in, and the contestants are struggling. There's £100,000 hidden in the jungle, waiting to be found, but the group are busy battling sleep deprivation thanks to an insect infestation. Plumber Jack wrestles a potential meal from the grip of a python, and crisis hits when the islanders realise there is a major issue with their water supply. Ex-marine Marco and hereditary peer Ivar are sitting on a secret stash of £35,000. They volunteer to lead the search for a new water source - but can they be trusted to put the interests of the group before their own?

The group are barely subsisting on coconuts and winkles. With suspicions on the rise about the hidden cash, Morag takes action that threatens to tear the islanders apart.

After seven days without a proper meal, the group of hungry and exhausted contestants start to fall apart as tensions around money continue to plague the camp. Meanwhile, 58-year-old Morag and 75-year-old Irene are keen to prove that age and gender mean nothing on the island, as they set about the difficult task of hunting some food.

After days of hunger and bickering over cash, the end is in sight for the Islanders. But with £35k still to be discovered, will people share the money or keep it for themselves?

Bear returns to Treasure Island to explore how the castaways coped for 35 days - with the brutal conditions, each other, and with the lure of hidden cash worth £100k.
