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.

Moody Welsh crime drama with a standout Kelly Reilly and strong supporting cast. A slow burn at first, but rewarding once it finds its pace. Highly recommend.
MovieGuys 6/10 Feb 21, 2026
Strong cast, intriguing crime thriller, but as per usual let down by dreary DEI baggage.

Let's start with the positives: the Welsh setting with a village under siege by rising ocean levels is a little unique. The crime drama, which spans two unsolved murders of children, is darkly disturbing with lots of twists and turns. Equally quality acting offers up well-rounded, often flawed characters.

The downside is by now wholly predictable. The incessant need to ram DEI messaging down the viewer's throat. Personally I find it downright tiresome and pointless.

In summary, it could have been a great series, but it's spoilt to a decent degree by the compulsion to inject woke narratives into what is supposed to be entertainment. An okay watch.
