Dexter, James, Olly and Reese try to build bridges with band member Blaise, who's feeling increasingly isolated from the rest of the band. In the training room, they try choreography wearing a blindfold in an attempt to master their moves, but will the band turn the corner and get approval from K-pop creator Heejun Yoon? They also immerse themselves in Korean culture as they visit a traditional folk village with K-pop legend Shindong, and they are taken to a Korean food market by the K-Pop Cowboy, who encourages them to sample some local delicacies, including pig's trotters, chicken feet and octopus. Have they got the nerve to try everything?
