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.Cefin's death summons Jackie's former partner, Detective Eric Bull, back to Morfa Halen to lead the investigation into a community he failed once before. Convinced the cases are linked, Jackie and Bull must reconcile and race to uncover long-buried secrets inside Morfa, before the storm breaks and all the evidence is gone for good. An intimate and cinematic story, Under Salt Marsh takes audiences into the heart of a community bound by nature and fractured by an unthinkable crime.
