Series 1-3: 20 x 60 mins
Drawn back to her childhood home for personal reasons – the faltering health of her beloved father – DCI Cadi John finds herself policing the precinct and people of her youth. It is a job she enjoys. However, when the body of a local woman is found in a remote river, Cadi's world – and the world of those around her – is changed forever. When another local girl goes missing, what began with a murder investigation, quickly escalates into a race against time; a desperate search to save the life of a vulnerable young woman held against her will in a ramshackle compound in the mountains. Series 2 picks up nine months later, as the brutal murder of an ex-teacher is discovered following an anonymous phone call and Cadi must lead an investigation in the slate-strewn mountains of Blaenau Ffestiniog.
