What is Deadwater Fell about?

• REVIEW: Dark Channel 4 drama Deadwater Fell packs an emotional punch

Tom Kendrick is a well-liked GP in a small Scottish village, Kirkdarroch, where he lives with his wife Kate, a primary school teacher, and their young daughters.

Jess is Kate's best friend and colleague, who moved to the village six years ago and got together with Steve, the local police sergeant.

The illusion of a perfect relationship is left "shattered" on one fateful night, when "the community is drawn to Kate and Tom’s family home in the forest by the flicker of flames and the smell of smoke," says the show's official synopsis.

"Amid the confusion of the house fire, Kate and her three children are found dead, and Tom, who is found alive, is rushed to hospital. It soon becomes apparent, however, that Kate and her children weren’t killed in the fire and the village realise that something unspeakable has happened."

Suspicion immediately falls on Kate, but Jess refuses to believe her best friend could be capable of such a terrible crime and is desperate to uncover the truth — no matter the cost.

Deadwater Fell is written by Daisy Coulam, the woman behind ITV's Grantchester.
