Over the summer, Rinn stopped taking her bi-polar meds and blames herself and the voices she heard for her grandmother's tragic death. To get a new start, Rinn and her mother are moving back to her mom's small hometown and Rinn has promised to never miss a pill again. The fresh start is just what Rinn needs. She falls in with the popular girls at her new school and she falls for very cute “farmer boy” Nate. But River Hills High School has a secret. The ghost of Annaliese, a girl who died when Rinn's mother was a student there, haunts a hallway the teens call The Tunnel. Rinn's not sure she believes it, but slowly Annaliese seems to be punishing those who enter the tunnel alone. A chorus soloist loses her voice, a star cheerleader falls off the pyramid, and then it gets worse-worse as in death. Rinn still doesn't know if Annaliese is real, and there's only one way to find out. Rinn needs to ditch her bi-polar meds again and see what the voices are really trying to say….
