Is there someone out there who looks exactly like you? Statistically, each of us could have up to seven doppelgängers in the world — and in this fascinating documentary, we follow a group of strangers on a global search to find their lookalike twin. From emotional first meetings to surprising life parallels, the pairs get to know each other while undergoing a series of scientific tests at St Thomas' Hospital. Using cutting-edge 3D facial scanning, 2D facial recognition, and DNA ancestry testing, experts explore just how deep these similarities really go. Finally, 100 members of the public are asked to rank the pairs from most to least alike — and the twin experts reveal which doppelgänger duo is the most genetically and visually identical.
