In this unique new survival program format, 45 male trainees will enter an extreme outdoor bootcamp, where they must survive rigorous physical training and reach the "top of the food pyramid" in order to earn a chance at debuting. The show will give birth to a new type of "wild idol" group through a never-before-seen survival contest.
