Morfa Halen is a close-knit Welsh community, precariously situated between towering mountains and a rising sea that poses a constant threat. When a rare storm approaches, Jackie Ellis, a former detective now working as a teacher, finds the lifeless body of her 8-year-old student, Cefin, apparently drowned.
