From east to west, the Irish border is a place of wildness and wilderness. In the beautiful, rugged land of Bandit Country, the job of policing falls to two separate police forces: the PSNI north of the border and the Garda in the south. When both are forced to work together to solve a serious crime, Detective Inspector Philip Boyd of the PSNI - straitlaced, teetotal, reactionary Presbyterian –finds himself working alongside his Garda counterpart, Detective Inspector Aoife Regan –foul-mouthed, unapologetically gay, and unwillingly seconded to what she calls ‘the boglands’.   

They rarely agree on anything and get off to a rocky start, but, whether they like it or not, they have crimes to solve – and unexpectedly begin to form a formidable crime-fighting duo.
