Johnny attempts to piece together his visions to fill in the large gap of missing time in his memory in order to figure out what happened to one of Stillson's campaign volunteers who mysteriously disappeared while she was with him.

Arrested for the murder of Rachel Caldwell, Johnny seeks the assistance of her sister, a reluctant Rebecca--who believes that he is guilty--and his friends to prove his innocence and help figure out what really happened to her.

The continuing strain of visions takes its toll on Johnny while he and Rebecca try to bring Stillson to justice for Rachel's murder, and Reverend Purdy confesses his sins.

Johnny is forced to try and save Greg Stillson...by stopping Rachel Caldwell from making a fatal mistake, even though it may cause nuclear armageddon.
