Season 4

Seventeen celebrity recruits have the guts to sign up for the most brutal Special Forces selection course. Their first initiation is to be set on fire, and then survive a plane crash simulation.

Celebrity recruits must remain calm in a terrifying balancing act high above a factory floor. Later, they face a dangerous Navy SEAL drowning survival test called 'the beehive'.

Entering a dark tunnel filled with obstacles and water, recruits must remain adaptable and battle claustrophobia. Tensions boil over as the recruits attempt to work together.

Recruits face a high adrenalin task as they leap from a moving zodiac into a moving helicopter. Pepper spray conditioning pushes some over the edge. Only with the right mindset will they succeed.

Friction among the recruits explodes as leadership is put to the test in a brutal Navy SEAL surf battle and a grueling team waterfall climb.

Recruits take part in an extreme tug of war. Facing off against each other, the loser will be dragged off a 100 metre cliff. An assault course will leave them bruised and battered.

In a heart-stopping abduction scenario, recruits must escape from the trunk of a moving car, bringing out reckless behaviour in some.
