How a simple DNA test turned a world upside down, leading to profound questions of identity. When 71-year-old Philip was given a genetic testing kit for Christmas, he assumed he would stumble across an ancient line of nobility or a novel identity to latch onto. Instead, he found himself unravelling a mystery with more twists and turns than a spiralling strand of DNA. David Reid meets an extraordinary group of people who sent in DNA samples and tested negative to the question: “Who am I?” Join them on a moving, funny and thought-provoking journey as they dig through layers of family myth and secrecy to unearth the incredible story of their origins. Produced and presented by David Reid Editor: Hugh Levinson Production Coordinator: Jacqui Johnson Sound: Tom Brignell
