Jack and his crew are off to the Sarawak jungle. Here they will live beneath the canopy for six days as they trek towards the home of the Penan, one of the last truly nomadic jungle tribes untouched by the 21st Century. This task will be make or break time for recruits' mental and psychical capabilities and with no hospital nearby, preparation for the journey is the ultimate key to survival.
