The show is based around the town’s local Garda Station, as well as the ongoing battles between two feuding families, the Kielys and the Hennessys, whose differences often involve them getting into trouble with the Gardaí. The series is filmed on location or in studios based at the old John Player Factory in Dublin. This includes an all inclusive Gardaí station, the Neptune Café and several home sets in the main warehouse. As Red Rock is set in a seaside town, Howth and Dún Laoghaire are often used for on-location shooting.
