A young girl is found brutally murdered in a small seaside town. The police are baffled; the town's inhabitants are panic-stricken. A serial killer is on the loose, and as yet more horrific murders take place, the search for clues becomes a desperate race against time. A tense psychological thriller with a chilling climax, this television movie introduced the charismatic, dedicated Welsh detective Noel Bain (Philip Madoc), a man with a passion for defending the innocent and an infallible instinct which the sharpest criminal minds cannot match. Also starring Hywel Bennett as Doctor Lewis, the feature-length drama won a BAFTA Cymru award and initiated the highly acclaimed, darkly authentic crime series which ran between 1997 and 2004.
