Saint Peter looms over Christian history as Jesus' first apostle and the traditional founder of the papacy, yet basic facts about his life and death remain contested. This film follows archaeologists working two excavation sites, one beneath the Vatican in Rome and one in Israel, as they reexamine bones, tombs, and inscriptions long tied to Peter's legend. Researchers walk through what recent digs have actually found versus what centuries of church tradition claimed, addressing where and how he died, whether the remains venerated in Rome are genuinely his, and how his authority over the early Church was constructed and later mythologized. Interviews with historians and archaeologists sit alongside footage of the excavation sites and relics themselves, weighing physical evidence against scripture and legend. Rather than simply retelling the familiar hagiography, the documentary treats Peter's burial and identity as an open archaeological question, showing how modern science is forcing a reassessment of one of Christianity's foundational figures.
