A small Welsh town was rocked by a nurse's brutal murder, all the more so because it was an apparent copycat of slayings that took place there 12 years prior. The cops who broke the original case-DI Ffion Lloyd (Elen Rhys) and DS Rick Sheldon (Richard Harrington)-were asked to take the reins, and would themselves additionally challenged by their foundered romantic past. Intriguing procedural co-stars Rhian Blythe, Ioan Hefin, Aled Pugh, Mali Ann Rees, Ian Puleston-Davies. 5 hrs. Widescreen; Soundtrack: English.
