Books nerds might recognise the title, as it’s based on the critically acclaimed, best-selling book of the same name by novelist Sarah Moss.
As well as a “tense” plot, and beautiful location shots, the upcoming series stars some TV greats including Emmy award-winning Dougray Scott, and Happy Valley legend Shirley Henderson.
Here’s everything you need to know about Summerwater on Channel 4, including plot, cast, location, and start date.

It looks at the “simmering tensions between holidaymakers that eventually erupt into a devastating climax”.
A synopsis tells us: “The story weaves together the lives of several families as they navigate unspoken conflicts, private dilemmas, and fleeting moments of beauty from their disparate cabins.

Is it based on a book?
Summerwater is based on the bestselling book of the same name by Sarah Moss.
The synopsis for the book reads: “It is the summer solstice, but in a faded Scottish cabin park the rain is unrelenting. Twelve people on holiday with their families look on as the skies remain resolutely grey. A woman goes running up the Ben as if fleeing; a teenage boy chances the dark waters of the loch in his kayak; a retired couple head out despite the downpour, driving too fast on the familiar bends.”
It continues: “But there are newcomers too, and one particular family, a mother and daughter with the wrong clothes and the wrong manners, start to draw the attention of the others. Who are they? Where are they from? As darkness finally falls, something is unravelling.”
Critics called it “a masterpiece”, and “so accomplished”.
It has been adapted by screenwriter John Donnelly (Utopia) and is directed by Robert McKillop (Guilt, Ludwig) and Fiona Walton (Shetland).
