A new concept of an extreme survival audition program takes place in the wild. The 45 applicants are evaluated for their skills and potentials rather than their stereotypical figure by revealing their instincts in the jungle-like entertainment industry. Kim Jong Kook, Cha Tae Hyun, Lee Sun Bin, model Lee Hyun Yi, Kim Sung Kyu, and Yujeong of Brave Girls help the applicants improve as an observer. Also, Tiger JK, Kim Jong Wan of NELL, and Lia Kim provide generous support as trainers. Applicants' physical strength and potential under extreme situations will be evenly evaluated. An unconventional audition program to discover and develop a rough diamond! Please look forward to seeing who will become the apex predator of this food chain!
