From the director of Broadchurch and the producers of Line of Duty comes “an interesting insight into one of the most important scientific breakthroughs in recent history” (The Independent, UK). Code of a Killer tells the fascinating true story of the discovery of DNA fingerprinting and its introductory use by police to catch a double murderer in the 1980s. When the trail goes cold on the homicides of two teenage girls, Detective David Baker (David Threlfall, Shameless, Ripper Street) contacts Dr. Alec Jeffreys (John Simm, Life on Mars), who has made headlines with his groundbreaking DNA research. Together they attempt what has never been done before—to solve a crime through DNA profiling. Facing public opposition and lack of funding, Baker and Jeffreys conduct the world’s first “DNA manhunt” to find the girls’ murderer and stop a serial killer in his tracks. This riveting miniseries also stars Anna Madeley (The Crown, Mr. Selfridge), Andrew Tiernan (300), Lydia Rose Bewley (The Royals), Farzana Dua Elahe (The Hundred-Foot Journey), and Robert Glenister (Hustle, Close to the Enemy).
