Set in the fictional Welsh town of Morfa Halen, a tight-knit community is nestled between mountains and a fast-encroaching sea that threatens its very existence. As a once-in-a-generation storm begins to gather far out at sea, former detective turned teacher Jackie Ellis (Reilly) discovers the body of her 8-year-old pupil, Cefin, seemingly drowned. “The discovery sends shockwaves through the community, reviving the ghost of an unsolved cold case that rocked the town three years prior — the disappearance of Jackie’s niece, Nessa, which cost her career,” a plot synopsis reads.

Under Salt Marsh is a crime thriller set in a community deeply connected to its environment, and interwoven with the heartache, fears, dreams and secrets of its people,” said showrunner Oakley. “At the heart of it all is Jackie, a character who embodies the wildness of the place we’re depicting. She’s free-spirited, compassionate and determined, with a steely resolve that makes her truly of the land. We’re absolutely thrilled to have Kelly Reilly bringing Jackie to life.”

Under Salt Marsh is produced by Little Door Productions in association with Sky Studios. The series is written by Oakley, Jonathan Harbottle and Nikita Lalwani. Oakley is lead director, with Mary Nighy directing episodes three and four.

Under Salt Marsh will be available on Sky and streaming service Now in the U.K., Ireland and Italy. NBCUniversal Global TV Distribution will handle international sales of the series.
