For the first time in 25 years the Australian SAS lift their strict veil of secrecy to reveal what it takes to pass the most physically challenging and psychologically demanding military selection process in the world. In a gripping two-part documentary, the program follows the journey of 131 hopefuls, who hail from the cream of the military, as they attempt the brutal 21 day trial. Most who start will never finish. This is the ultimate search for warriors.
