The eighteen celebrity recruits return to base camp for the final time to debrief with the DS and share their life-changing experiences on SAS selection.

The toughest test of their lives comes to a heart-stopping conclusion. Only five recruits remain – who has done enough to pass SAS selection?

Recruits are pushed beyond their physical limits on a merciless assault course, while a grim test of the heart leads to an outpouring of emotion.

Recruits are put under extreme pressure in a high speed, high intensity tactical driving mission, plus an unexpected ambush and an explosive dressing down.

Recruits play dirty when pitted against each other in a do-or-die test of true grit, and an excruciating 5km log haul through rugged terrain sees them dropping like flies.

The ultimate test in trust goes horribly wrong and a torturous casualty evacuation takes a devastating toll.

Recruits dig deep for a confronting backwards fall; an arduous physical test sees someone play dirty; their most shameful secrets are revealed.

Recruits face a terrifying test of fear down a steep 90m cliff face and a daunting mission in a pitch black tunnel. As Bra Boy Koby Abberton comes clean, another recruit is brought back to earth.

Recruits undergo a critical test of mental strength, in a kill or be killed scenario; a brutally cold ice drill stops some dead in their tracks; and a new duty recruit takes charge as others unravel.

Recruits must identify the weakest amongst the group. These individuals are then tasked with leading teams through a gruelling physical and mental task.

The celebrity recruits face a frightening casualty mission, plunging down a rope from a helicopter hovering above water, to learn how to turn their aggression on and off.

The celebrity recruits are submerged in a vehicle underwater, forcing them to control their panic while holding their breath. They also undertake a covert drill, to test their integrity.

The celebrity recruits must use courage whilst facing a terrifying balancing act, 30m above ground. Back at base, they face claustrophobia by negotiating a narrow underground tunnel.

18 celebrity recruits undertake physical and psychological tasks to strip them of their egos. On arrival, the recruits face a tear gas exposure and interrogation by the ex-special forces' instructors.
