Abby Tate, Mia&#x27;s twenty-one-year-old patient, has been in a coma for almost two years, kept alive on a ventilator.  When Abby unexpectedly wakes up to find herself a quadriplegic, she withdraws into her own inexpressible feelings of grief, loss, and fear.  As her memories return, it seems Abby is somehow unconsciously channeling some dark and vengeful power, a malevolent force that threatens to destroy everyone and everything around her.
