Yellowstone’s Kelly Reilly lines up Sky thriller

Under Salt Marsh is set in Morfa Halen, a fictional Welsh town (that translates to ‘salt marsh’). Nestled between mountains and the unforgiving sea, the tight-knit residents are under threat from their very surroundings.

Reilly’s character, Jackie Ellis, enters as a former detective turned teacher. As a brewing storm comes towards Morfa Halen, Ellis discovers the body of one of her pupils, an eight-year-old called Cefin.
