This series will revisit these horrendous, cold case murders to take the audience on a journey across the badlands of Ulster in the four decades between 1973 and 2005. Behind each story is the bubbling context of the Northern Ireland of the time, a place engulfed in sectarian conflict.Episode four tells the inside story of the murder of Marian Beattie. In 1973, the Portadown teenager had travelled with her brother and friend to attend a charity dance in Aughnacloy. The body of the 18-year-old girl was found at the foot of a cliff in a quarry along a narrow country road.
