Three Identical Strangers tells the astonishing story of three men who make the chance discovery, at the age of 19, that they are identical triplets, separated at birth and adopted to different parents. The trio's joyous reunion in 1980 catapults them to fame but it also sets in motion a chain of events that unearths an extraordinary and disturbing secret that goes far beyond their own lives - a secret that might one day answer key questions at the heart of all human behaviour.
