It's the go-to Christmas present for the person who already has everything. A gift that promises to tell you who you really are and how you're connected to the world. Millions of us have spat into a tube and sent a vial of our DNA to a company like Ancestry and 23andMe. Their tests promise to unlock the truth of our heritage - perhaps even a future foretold in our genes. Across six episodes, Jenny Kleeman meets the men and women whose lives changed forever after they opened a box that contained a DNA test. Exposing scandals, upending identities, solving mysteries and delivering life-changing news - Jenny investigates what happens when genealogy, technology and identity collide. Episode 1: Fraud A scandal deep in the heart of London's Harley Street is exposed when a man in his eighties receives a DNA test Christmas present from his daughter.
