Socially awkward─yet highly skilled─Det. Sgt. Sean Stone (Reece Shearsmith) has alienated enough higher-ups on the police force to get himself stuck in a low-level missing persons unit. Partnered with analyst Ruth Hattersley (Alex Kingston), Stone is soon putting his talents to good use tracking down serial killers in a pair of perplexing cases. This gripping, four-part British miniseries also stars Don Warrington, Noel Clarke, Adjoa Andoh. 183 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital stereo.
