More than 99 percent of the evidence proves the Shroud of Turin is the authentic burial cloth of Jesus Christ. Only one test says otherwise—the carbon date performed in 1988.
A serial killer with a fetish for fire targets the faithful of Tucson, Arizona. Homicide detective, Pete Johnston, works to catch the killer before more clergy are killed, before more churches are burned.
His daughter, Amari, is a criminal justice major at the University of Arizona. When the Shroud is carbon dated at her university, the results reveal that the relic is a medieval forgery. Amari investigates this ancient cold case file for a class project and makes a shocking discovery that could alter the fate of Christianity.
She teams up with Dr. Kevin Brenner, a brilliant young experimental physicist, and together they gather evidence so they can plead their case to the Vatican—unless the killer can stop them first. Her father desperately tries to protect her and catch the killer before she becomes his next victim.
