Musical/drama actor Oh Man Suk, Big Bang's Daesung, and rising stars Im Joo Hwan, Im Joo Eun, and Kim Ji Won take part in this drama about the trials and tribulations of students enrolled in the theater department of a university. Jang Jae Hun (Im Joo Hwan) is a high school dropout who roams the streets at night with his two best friends pickpocketing drunkards. Park Tae Hee (Kim Ji Won) lives in the countryside with her grandfather, and inherited her musical talents from her rock star father. Ha Do Sung (Daesung) composes songs under the guise of singer HADES, but he quickly leaves the music industry when his identity is nearly revealed to the world. Kim Byeong Gun (Jo Jung Suk) is the odd one out in his family of businessmen, wishing to pursue a career in musicals - despite his debilitating fear of performing in front of others. Eun Chae Young is an experienced film actress, but she has the desire to prove herself on the musical stage. What she doesn't expect is to be challenged by Oh Doo Ri (Im Joo Eun), an equally talented actress who prefers to spend her time playing first-person shooting computer games than rehearsing. These young adults end up together in the musical department of Haneul Arts University, and find themselves under the guidance of unconventional professor Sunwoo Young (Oh Man Suk). With each passing day, they get a chance to learn what it is to be a 'star,' and to prove to the people around them that they can succeed in their chosen path.
