Callan (TV series) is run by Colonel Hunter. ("Hunter" is a pseudonym for the current Section Chief, like the C of SIS.) The Section removes those who pose a danger to the "innocent" by persuasion, blackmail, extortion or death. David Callan had been the Section's top operator but he had become too curious about his targets and the rationale for their removal. The Section considered him vulnerable, volatile and dangerous and had laid him off to a dead-end book-keeping job for an ungrateful employer. ABC then commissioned a series of six episodes in 1967. In the first episode Callan rejoins the section in
Callan (barony) from north of the county, Fassadinin, Gowran, Ida, Kilculliheen, Iverk, Knocktopher, Kells, Callan, Shillelogher, Crannagh, Galmoy. Callan lies to the west of the county, with the baronies of Shillelogher to the north and Kells to the south. Unusually for a barony, it contains only two civil parishes Callan and Killaloe. It is made up of 65 townlands. The Kings River flows through it, and was previously called the Callan River. Places of interest include Callan Motte and Callan Augustinian Friary. Today it is part of the Roman Catholic Church diocese of Ossory and the Church of Ireland diocese of Cashel
