River, a new Ghoulette for the band Ghost, is multi-talented. She can play bass guitar, regular guitar, and sing. When she goes on tour with them for the first time, her world is about to be turned upside down. While she does get along with the other ghouls and ghoulettes, there's one in particular who enjoys teasing her on and off stage. The question is, was he doing it just for show, or is there something more?
