 Although the drama was set in a near future world, in an immigrant exclusion zone guarded by advanced electronics, the real-life background was that Polish landscape which adjoins the eastern border of Germany and the EU, populated by a mass of refugees and dislocated people.The dark thriller focused on an investigation of an apparent race murder, leading to a disturbing underworld of would-be immigrants, border police, corruption and cover-ups.While Pirie's film noir-influenced works may be among the most satisfying of television's occasional excursions into that cinema style, it is with his Gothic screenplays that he excels as a genre writer.
