[4] Jack Whelan is a former Los Angeles Police Department (LAPD) detective who is asked to investigate strange occurrences related to a string of attempted suicide.
He concentrates his search on a secret society, Qui Reverti (Latin for 'who return'), whose members chase immortality by seeking refuge in the bodies of others after their own deaths.
In Whelan's case, this process destroys his marriage when his wife's body is taken by an intruder.
A serial killer named Marcus Fox comes back to life in the body of a little girl.
The struggle is exacerbated when the little girl becomes aware of the Qui Reverti guidebook for returning souls and begins using the information without truly understanding it.
