The directing staff apply pressure to the last eight recruits, exposing hidden personality traits before sending them into a gruelling 12-hour jungle mission high in the Andes

The last 12 recruits' trustworthiness is tested. The directing staff sow distrust among them and they identify their least trustworthy teammates, before an abseil trust exercise.

Chief Instructor Ant and his elite team test whether the remaining recruits can control their aggression, with a brutal game of murderball and the non-stop 'sickener' exercises.

The recruits face a terrifying bridge leap before they can find their base. The jungle environment, altitude and insects take their toll, and the DS give special attention to two volatile individuals.
