Paul Callan works as an investigator of miracles for the Archdiocese of Boston. Growing weary of his job and the tests it places on his faith, he takes a leave of absence and travels to Arizona to work on an Indian Reservation.

While there, Father Calero calls him and asks him to investigate a young boy, Tommy Ferguson, who supposedly has the power to heal others. Skeptical at first, Paul meets with Tommy and witnesses his abilities. He discovers that the young boy is dying, and that every time he heals another, his own health deteriorates. He also learns that his path and Tommy's are somehow inexorably linked.

When Paul is in a potentially fatal car crash, Tommy uses his power for the last time, and gives his own life to save Paul. As Tommy heals him, Paul sees the words, ""God Is Now Here"" written in his own blood.

His faith renewed, Paul returns to the church but the Monsignor dismisses his findings, causing him to resign. Paul is then approached by a stranger named Alva Keel who tel

SQ are called to investigate when a woman seems to be miraculously healed after a diner robbery where her neck was sliced. Keel begins to fall for her, but Paul suspects she's lying, and he and Evelyn soon discover ""Saint Debbie""'s secret. But they soon discover that there are such things as small miracles.

Paul and the gang investigate a haunted real estate office. Everyone who works there is convinced that there is a ghost, all except Larry Kittredge, the owner. Paul and the others discover that Larry believes the ghost is his dead son who has come back to him. As the hauntings worsen, SQ must convince him that it is he, not his son, who is responsible.

A friend of Paul's begins to receive letters from her deceased father. Paul tracks them back to an inmate on death row for murder (he was a hit-man). Paul learns that the inmate is responsible for the death of his friend's father. The inmate, who is illiterate, has been convulsively writing letters to the relatives of all the people he ever killed, and he believes that this is a sign that God has redeemed him.
