Season 1 of Touching Evil premiered on April 29, 1997.

Maverick police detective Creegan is the newest member of London's Organised and Serial Crime Unit (OSC), an elite, rapid-response crime squad. The OSC uses their diverse crime-fighting skills to bring justice to society. Along with his stalwart partner D.I. Susan Taylor, Creegan squares off against some of England's most dangerous criminals; a serial murderer of children, a killer intent on murdering hospital patients, and a cyber-criminal who lures young Web-surfers with a Gothic fantasy game and manipulates them into committing violent crimes.

Season 2 of Touching Evil premiered on April 29, 1998.

This time out, Creegan & Taylor with the Organised and Serial Crime Unit have their hands full after some deeply disturbed criminals. One is a serial kidnapper-murderer whose fatal fascination with young women leaves Creegan with a new scar to bear. Another is a profoundly disturbed relief worker whose nightmares of atrocities committed in Bosnia impel him to erase the memories of fellow aides permanently; and the last is an international ring of baby brokers.

Season 3 of Touching Evil premiered on May 16, 1999.
