Touching Evil focuses on two extremely successful and highly skilled detectives, Detective Inspector Dave Creegan (Robson Green - Soldier Soldier, Reckless) and DI Susan Tayler (Nicola Walker - Cruel Earth, Moll Flanders) who work in the Organized and Serial Crimes unit (OSC), a crack team of special police agents. Touching Evil follows the OSC as they use their diverse skills to bring to justice the most dangerous criminals. Touching Evil follows the unit, a newly conceived organization committed to dealing with the growing spectre of serial crime in the UK. D.I. Creegan has just returned to work after recovering from a bullet in his head, yet his intuitive detective skills are incredible.
