Eighteen Aussie celebrities volunteer for the toughest test of their lives - a condensed version of the Special Forces selection course, which will physically and mentally strip them back to the core.
Recruits face a terrifying test of courage, 30 metres above ground, before a claustrophobic underground wormhole task which gets smaller and smaller the further they go. Plus, Emma Husar exposed.
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.
Recruits must identify the weakest amongst the group. These individuals are then tasked with leading teams through a gruelling physical and mental task.
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; a new duty recruit takes charge as others unravel.
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 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.
A high-speed, high-intensity tactical driving mission puts the recruits under immense pressure; an explosive dressing down and an unexpected ambush make things difficult for the recruits.
