Elliott Smith wakes up in the hospital with a head injury...and an invisible companion. At first, he's convinced -John- is just a figment of a damaged brain, but when Elliott is fully recovered John is still around--and desperate to find out who he is. Reluctantly, Elliott agrees to help, and discovers Chicago PD has a John Doe on their hands with six bullets in him--who died in the ER at the same time Elliott was there.
As Elliott digs deeper into the mystery of John, he stumbles on a body hidden behind a wall for 80 years, meets a sexy artist who could become more than just a one-night stand, and uncovers a deadly secret that has haunted a nun for two decades.
