Like its predecessor Dream High, it follows a group of students at the Kirin High School of Art stars who pursue their dream of becoming K-pop stars. However, it has a slight difference in terms of plot with its new set of student casts.
After going into financial bankruptcy, Kirin High School is taken over by Oz Entertainment. The company then transfers its own young trainees to circumvent a law requiring underage entertainers to study for a set amount of time. Competition brews between the troubled students at Kirin High, and the newly transferred Oz Entertainment trainees.
Although Shin Hae-sung (Kang So-ra) enters Kirin High School with a high exam score, she has no talent in singing. She meets and befriends fellow students, Jin Yoo-jin (Jung Jin-woon) and JB. Yoo-jin, who originally got into the entertainment industry as a child actor, is now troubled by his dreams of becoming a rock star as he tries to cope with the pain of his parents’ divorce. JB, a member of a famous group I:dn (Eden), develops feelings for Hae-sung and dates her later on.
Ri-an (Jiyeon), a member of a famous girl group called HershE, chases after JB, who was once her boyfriend. Meanwhile, Yoo-jin, who also likes Hae-sung, tries to separate the couple with Ri-an. Later on, Ri-an and Yoo-jin give up and remain close friends.
Hae-sung leaves for the US, and 8 years after their graduation, it is revealed that she is now a famous composer and director. JB, due to his leg injury, gives up on his dream of being a dancer and ends up as a music producer. Ri-an becomes a Hallyu idol, and Yoo-jin becomes a rock music teacher at Kirin High School by day and a rocker by night.
All of them have a reunion performance on stage for Kirin High School’s 17 years anniversary.
