Plot Summary
Morfa Halen is a tight-knit Welsh town precariously nestled between towering 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 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.
What Works
- Solid entry in the crime, mystery catalog
- Stunning cinematography and production design that demands a large screen
- A compelling lead performance that anchors the entire narrative
What Doesn't
- A few minor subplots feel slightly underdeveloped
- May feel overly familiar to long-time fans of the genre
