From the recruits' very first challenge - a terrifying backwards dive out of a helicopter - Ant Middleton and his team are determined to show there will be no allowances made. Later, the celebrities have to overcome more fears.

Twelve celebrities, from Katie Price to Joey Essex, leave their glamorous homes to take on the SAS selection course, the toughest challenge of their lives. Who will pass this test?

A behind-the-scenes look at what happens when the celebrities leave the jungle and return to VIP paradise - meeting the celebs' friends and family and get to know them as they wait nervously each day in camp to see who is leaving the jungle.

It's the final and the remaining celebrities are facing their toughest trials yet, but only one will get the votes needed to be crowned as King or Queen of the Jungle.

Chief instructor Ant Middleton and his directing staff put the celebrity recruits through a series of tests. One celebrity recruit collapses on a mountain and another is badly affected by the extreme cold, as they face brutal challenges.

The celebrities are paired up to prove that they're team players, and must put their lives in each other's hands, in a terrifying free fall abseil. They must leave their celebrity world behind and learn to trust their partner to keep their place.
