Hidden is a gripping serial made up of inter-weaving narratives, all of them linked by a single crime - the abduction and incarceration of three young women, held in captivity, high in the hills by a local man.
 
Hidden is the eight-part crime drama from the award-winning makers of Hinterland.
From picturesque Bangor, overlooking the churning waters of the Menai Straits, to the abandoned quarries of Llanberis; from the mountains of Snowdonia to the wind-swept Llyn Peninsula, this is a landscape DCI Cadi John knows well. A world she never expected to return to.
 
When a young woman's body is discovered in a remote river, a murder investigation is launched. However, it quickly escalates into a race against time when a female student goes missing. Could it be that the killer has struck again?
