Robert Beckford, professor of theology, sets out to find what happened to the people who shared Jesus's bloodline rather than just his teachings. The New Testament names brothers, including James, who led the early Jerusalem church after the crucifixion, yet mainstream Christian history has largely dropped them from the story. Beckford works through historical archives and early church records, asking why a family so central to the first Christian movement gets pushed to the margins by the fourth century, when doctrine settles around Jesus as a singular, unmarried figure with no descendants. He weighs the evidence for a continuing bloodline against centuries of church tradition built to deny one, and considers what a confirmed family line would mean for doctrines resting on Jesus's uniqueness. The film stays with Beckford's own inquiry rather than staged reenactments, following him from question to archive to argument as he builds the case for a hidden family history.
