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.

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.
