The Heat Is On - Season 1

Beginning a six-part reality series in which 14 strangers from varied backgrounds strive to prove themselves. This they do by surviving a punishing SAS-style training regime in Scotland, and other remote and harsh environments across the globe, while attempting to avoid the ultimate sword of Damocles - being voted out by the others.

Second in a six-part reality series in which 14 strangers strive to prove themselves by surviving a punishing SAS-style regime in locations across the globe. On day four of the challenge the volunteers have barely eaten when SAS expert Lofty Wiseman puts them through a 5-mile hike and a raft-building exercise. Adam Krug falls into the icy waters of Loch Ness, and there's the horrors of the Phobia Tank, full of spiders, snakes and scorpions.

A week into the challenge, in the third programme of a six-part reality series, and the contestants are hungry and tired. Andre makes a nightime raid on SAS expert Lofty's food stores but the whole group pay with an interrogation the next day. At the airport, the names of those who have been selected to go on to the next round are revealed and the qualifying group sent on their way to the new location.

The fourth programme of the six-part reality series sees the select eight competitors being dropped by helicopter 5,000 feet up a mountain in Peru, their aim being to find rendezvous points that will provide them with supplies.

Continuing the endurance contest. The eight volunteers find the going tough as they enter the deepest part of the Peruvian rainforest. Concern over Sheila Blackburn's injury helps draw the group together but exhaustion and starvation are beginning to take their toll. Will the group stand up to self-appointed leader Andre?

In the last programme of the reality series the select eight embark on a final river challenge - to travel 50 kilometres down the treacherous Rio Blanco. Whatever the final outcome, there is sure to be plenty of high drama on the way.
