Red Riding: In the Year of Our Lord 1983 (TV)

A murky tale. A child goes missing in West Yorkshire, one of several over ten years; the police find a patsy, an acquaintance of Michael, a blood simple man serving a life sentence for another girl's death. Michael's mother asks John Piggott, a burned-out solicitor, to look into her son's conviction; Piggott finds injustices in current and past cases. Maurice Jobson, part of a group of corrupt cops, searches for the missing girl, involves a medium, finds nothing, leans hard on Piggott, and may be tiring of the sham. He's warned off going soft. Is there moral strength anywhere capable of facing down the cabal? - IMDb
