Frederick Bligh Bond was a respected Edwardian archaeologist hired to excavate Glastonbury Abbey, and this film traces how his dig turned into one of the strangest episodes in British archaeology. Convinced the abbey held clues to King Arthur's grave, Bond began consulting a psychic collaborator who claimed to channel the voices of long-dead monks through automatic writing, guiding excavation decisions through séances rather than surveys. The film follows his finds at the ruined abbey grounds, weighing what his methods actually uncovered against the reputational cost once the Church of England learned how he worked. Historians and archaeologists on camera unpack why a credentialed professional turned to spirit communication, what the Edwardian fascination with the occult and the afterlife had to do with it, and how his case still gets cited as a cautionary tale about evidence and belief. The result is part detective story about Arthurian legend, part portrait of a career ruined by its own methods.
