Joo Byung-hee (Lee Min-ki) is the crazy, free-spirited leader and vocalist of the popular underground rock group, Eye Candy. Joining him is Kwon Ji-hyuk (Sung Joon), chic Lee Hyun-soo (Kim Myung-soo), playboy Kim Ha-jin (Yoo Min-kyu), silent Jang Do-il (Lee Hyun-jae) and baby-faced Seo Kyung-jong (Kim Min-suk). When their delinquent-ridden school is forced to close down, they debate whether it's even worth returning to high school at all. However, due to an outside confrontation with their new school's current ruling band, Strawberry Fields, Eye Candy decides to attend Jungsang High out of spite so they can rule the school once again.

Shut Up Flower Boy Band is an atypical music drama – gritty, relentless and highly stylized to the punk sentiment, but always with heart.
