Well, statistically, it is estimated that for every face there are 7 doppelganger matches around the world. In this documentary, we follow a scientific study that is bringing strangers together from around the globe that bear a striking resemblance. While the pairs get to know each other, they undergo a series of tests by the twin-experts at St Thomas' Hospital, London. These include measuring similarities of facial features using the latest 3D scanning technology, 2D facial recognition analysis and DNA testing. The experts then get 100 people to rate the similarities from photos from most alike to least alike. Taking all of the results into consideration, the twin-experts will then reveal which pair is the most identical and why.
