Kim San (Kim Joo Young), Dok Go (Jo Sung Wook), Tae Ha (Jo Sung Woo) and Joo Pil (Oh Song) ? want to do whatever it takes to make it in the music industry. But success is not determined by sheer hard work alone. Their manager, Hwang Jwa Soo (Park Sung Woong), has a bad history with Goo Bon Keol (Lee Joo Hyun), the president of Major Entertainment, which makes it difficult for the band to get a fair shake.
