Based on Lynda La Plante’s best selling novel, rookie DC Anna Travis (Kelly Reilly) takes her first case, seven women brutally and ritualistically murdered. Under the unorthodox guidance of DCI James Langton (Ciarin Hinds), Anna uncovers information linking one man to each victim. Alan Daniels - a much-loved and respected actor. Seemingly above suspicion and impossibly handsome, even Travis may not be immune.
