The story begins in Bonita's antique shop in Monmouth, where a routine house clearance turned up film canisters, some of which contained footage going back to the First World War. An architect called Danny Sullivan, who also happens to be a writer on the occult, bought the films and then claimed they contained footage of the Angels of Mons. He also claims that he sold the film footage to Hollywood for half a million dollars. Chris Morris explores the incredible myth of the Angels of Mons and why it has been resurrected almost a hundred years after the original event.
