We revisit the volatile decade that was the 1970s, Chris and Paul Dawson’s heyday. They were at the peak of their celebrity as well known sporting figures and male models, exploiting the novelty of being identical twins in everything they did. Many years later as police close in over Lyn’s suspected murder, phone-taps capture more conversations between the brothers and within the Dawson clan. And we take a look at the role of the meticulous young Homicide Unit cold case detective who first became involved in 2015 and ultimately brought the murder case to court.
