Ulrika Jonsson and Kerry Katona are among the latest celebrity recruits facing the gruelling tasks and interrogations that make up SAS training. In the first episode, they must brave an aerial assault course designed to test how candidates manage fear, and carry out a hostage rescue in a building that has been exposed to CS gas.

The remaining celebrities are put into pairs for 48 hours of trust exercises, beginning by rappelling down a 100-foot rock face, relying on their partner to break their fall. Once the task is complete, they must run three kilometres back to the van, but Ore Oduba struggles, leaving him and his partner Shanaze Reade stranded on the mountain overnight. In the final task, the recruits carry a 40kg fuel drum in pairs across four kilometres of gruelling terrain.
