The Christian Bible left behind a trail of objects that believers have spent centuries trying to track down: the cup Christ drank from at the Last Supper, the shroud said to have wrapped his body, and other relics claimed by churches, museums, and private collectors across Europe and the Middle East. This compilation follows historians and researchers as they dig into the provenance of the Holy Grail and the Turin Shroud, weighing medieval chronicles, forensic testing, and carbon dating against the legends that grew up around each object. Experts walk through the competing claims, the forgeries exposed along the way, and the reasons some relics keep surviving scrutiny while others collapse under it. Rather than settling on belief or debunking, the film treats each artifact as a case file, tracing how a physical object becomes a holy relic and what happens when science gets a chance to test the story. It is less about faith itself than about the evidence people have used to defend it.
