New Wales-set detective drama Under Salt Marsh has confirmed a release date for early next year. The "gripping" series has also unveiled a new trailer, teasing the tense events to come.
The Sky show focuses on a "once-in-a-generation storm" as a former detective (played by Kelly Reilly) makes a horrific discovery in the aftermath.
It has now been revealed that the series will premiere on Sky and NOW on 30 January, 2026, with a new trailer expanding on a recent teaser.
The preview sees Reilly's character Jackie Ellis find a body, and she's determined to get to the truth before the storm makes landfall again. However, Jackie is warned that she'll be "sorry" if she points the finger towards anyone in the community.
Under Salt Marsh follows the character's discovery, which "reopens the wounds of a three-year-old cold case which cost her both her career and her family's trust".

"Forced to reunite with her estranged police partner Eric Bull (Rafe Spall), Jackie is drawn back into an investigation that will shake Morfa Halen to its core," the synopsis adds.

The Crown's Jonathan Pryce, Trigger Point's Mark Stanley, Bad Sisters' Brian Gleeson, Industry's Harry Lawtey, Chimerica's Naomi Yang and Treason's Dinita Gohil also star, while Claire Oakley has created, written and lead directed the series.
"We are incredibly fortunate to have such a talented cast bringing these characters to life," producers Little Door's CEO Elwen Rowlands previously said.
"Claire's compelling scripts tell a thrilling story of a community deeply connected with its environment, raw with emotion, and beautifully mirrored by the stunning backdrop of North Wales where the story unfolds."
