The second series will see a trio of young performers join the cast in antagonistic roles.
Annes Elwy (Little Women) will play Mia, a disturbed teenager who gets a kick out of manipulating people and has a bad relationship with her mother.
Steffan Cennydd takes the role of Connor, a 16-year-old boy who moves to the area to escape his physically abusive father, only to fall in with Mia who proves to be a bad influence.
Last but not least, Siôn Eifion has been cast as Lee, Mia's cousin struggling with a toxic home life who feels he has always lived in her shadow.
What is Craith/Hidden about?
After the body of a former teacher is discovered in a house on an estate in the mining town of Blaenau Ffestiniog, DCI John and DS Vaughan are called in to investigate the case.
Three local youths, Mia, Connor and Lee, are suspected to be involved in the murder, but the case becomes even murkier when rumours about the victim's previous misdeeds come to light.
Alongside their work on the case, Craith/Hidden series two will also delve into the personal lives of DCI John and DS Vaughan, the former coping with the recent death of her father and the latter getting to grips with caring for his newborn baby.
Where is Craith/Hidden filmed?
The noir drama is filmed largely on location in Blaenau Ffestiniog, a town located in North Wales that showcases the mountains and slate quarries of the area.
DCI John lives in a unique house that is cut off from the Welsh mainland. This setting is filmed on the Menai Strait, a narrow stretch of water that separates Anglesey from the rest of Wales.
