Vampires and murder backstage in a Christchurch theatre. 16 year old Riley Lowe is working as a stage hand, backstage at her theatre company's annual show. Her classmate from school, Tasha, is also in the show as a dancer and, as usual, she is flirting with all the guys. In particular, she is trying to take the one Riley is attracted to. Severn is one of a group of professional theatre crew who are helping with the show but the closer she gets to him, the more Riley realises that there is something strange about the group who live and work in the dark.
When Tasha is killed and Severn disappears, Riley learns their terrible secret. But can she solve the murder in time to save Severn?
