In a community nourished and sustained by myth and bordered by untamed nature, the search for a serial killer becomes a matter of life and death for local detective Annie Redford who is trying to cope with her first murder case. When the body of local man Niall Swift is found at the foot of Carn Mohr Mountain and an isolated human heart on the loch shore, the town's normality is shattered and the nightmare begins.

Written by Stephen Brady (Fortitude, Vera, Silent Witness), The Loch, released on DVD 17th July 2017 from ITV Studios Home Entertainment, introduces Annie and her family - husband Alan, a tour boat operator on the loch and their only child Evie, who at 18, is about to leave home for Australia. The Redford's are an ordinary loving family with an ordinary set of problems, yet the pressure of a murder investigation will undermine their stability and create tensions that threaten to disrupt and destroy their lives together.

Within the tightly knit community, several local characters will come under suspicion as the monster lurking in their midst begins to terrify and rock the village to its core. Forensic profiler, Blake Albrighton, will assist on the case offering insights borne from the last four cases he's helped crack with his distinctive way of working.

The Loch stars acclaimed actors Laura Fraser (Houdini and Doyle, The Missing, Peter & Wendy), Siobhan Finneran (Happy Valley, Benidorm, Downton Abbey) and John Sessions (Upstart Crow, Florence Foster Jenkins, The Rack Pack) alongside Don Gilet (Brief Encounters, Holby City, EastEnders), Gray O'Brien (The Daniel Connection, Titanic: Blood and Steel, Coronation Street) and William Ash (The Tunnel, Moving On, Death in Paradise).
