SAS: Are You Tough Enough? - Season 2

The SAS's recruitment and training regimen is legendary for its relentless rigour. This second, six-part series relocates to the Borneo jungle, one of the most hostile environments on Earth, as 18 men and six women undergo the brutal selection process re-created by ex-SAS soldiers. Which volunteer will crack on day one?

Day four, and already ten of the original volunteers have dropped out. In part two of the series, Sergeant Eddie Stone and other ex-SAS soldiers put the remaining 14 contenders through 24 hours of physical hell in the thick, hostile jungle of Borneo.

The exhausted, sleep-deprived volunteers are put through a torrid night of interrogation. In the third of a new six-part series, how many will crack when subjected to stress positions, white noise and brutal questioning?

Nerves fray as the remaining eight exhausted and sleep-deprived volunteers are sent on an undercover reconnaissance mission. In the fourth of a new six-part series, how many will crack during the physical and psychological pressure of another long night on the jungle floor of Borneo?

From 24 volunteers chosen to undergo gruelling SAS training in Borneo, only six remain - three men and three women. In the penultimate programme, the group have to set up a river ambush behind enemy lines, and are thrust into real-life soldiering.

It's the final reckoning for the four remaining volunteers struggling deep in the Borneo jungle. Their ultimate mission is to attack an enemy camp. But whose performance will most impress Eddie Stone and the ex-SAS instructors?
