A new K-pop group is on the horizon, and a group of aspiring male singers, including a few established stars, compete for the opportunity to join the band and take on the charts. The contestants are split into two groups: the South Korean K-group and the global G-group, consisting of trainees from China, Japan, and other parts of the world. The trainees undergo a series of rigorous challenges, and as the show progresses, they must compete for viewer votes to secure their place in the top spots. Those who fail to make the cut will be eliminated. The contestants receive guidance and mentorship from a team of experienced professionals, including the singer-songwriter Lee Seok Hoon, the vocal coach and EXID member Solji, the NU'EST member and actor Hwang Min Hyun, and the dance star Lip J. As the competition heats up, which contenders will make it to the final round?
