After surviving the tragic car accident that claimed her parents when she was a child, Mita awakened to a strange gift — the ability to see and hear spirits. Now seventeen, she works part-time in a small musical instrument shop, where one fateful evening she stumbles upon an unusual band: a group of musician ghosts. What begins as a haunting encounter soon blossoms into an unlikely friendship, as Mita joins them in playing music that bridges the worlds of the living and the dead. Their performances, captured on video, explode across social media, drawing global attention for their unearthly brilliance. The sudden fame earns them a chance to compete to become one of the top six acts in a major K-Pop concert, but with opportunity comes peril — shadows close in, and Mita and her ghost friends must fight to protect her gift before it is stolen and twisted for darker purposes.
