Eighteen Australian personalities take on a condensed version of the Special Forces selection course.

The most difficult test of the recruits' lives comes to heart-stopping end; with only five recruits remaining, they hope to have done enough to pass SAS selection.

The recruits face a shocking test of courage 30 metres above the ground and a claustrophobic underground task.

All 18 recruits arrive back at base camp for the last time to debrief with the DS and open up about their life-changing experiences.

Recruits undergo a test of mental strength in a kill or be killed scenario; a brutally cold ice drill stops some recruits dead in their tracks.

A merciless assault course pushes the recruits to their physical limits; a grim test of the heart causes an outpouring of emotion.
