The instructors give the recruits a shock start when they arrive at the camp as they have to swim to the beach in freezing cold water. On the same day, one of the toughest exercises awaits them.

Recruits work in pairs and face nerve-wracking exercises at high altitudes where it is important not to be paralyzed by fear of heights. They are also pitted against each other in a tough physical challenge.

The instructors hint that there is a mole among them, spreading uncertainty and speculation among the group. The recruits are asked to rappel down a 120-meter rock face headfirst.

Halfway through the training, some of the recruits' leadership skills are put to the test when they have to lead the effort to free an off-road vehicle and transport an injured comrade up a waterfall. The exercises take their toll and the group is further decimated.

The recruits are very tired and some are beginning to doubt their abilities. The first part of the day takes place in an old abandoned mine shaft where the recruits have to balance on two ropes to a flag, 20 meters in the air.

Now comes the toughest day yet that will challenge the recruits' ability to stay together in the cold and continuous hardship. They are transported to a remote beach by the sea where an ice-cold bath awaits.

It's time to screen the group so only the strongest physically and mentally remain for the final phase. In an extremely challenging water element, their ability to control air hunger and claustrophobia is tested as they swim through a barrel in deep water.

In the final 24 hours, the remaining recruits are subjected to a series of grueling nighttime fitness sessions before the most brutal part of the selection process - the final interview.
