Detective drama fans, we’ve found your next binge-watch! Borderline is the impossible-to-fault crime drama coming to ITVX this autumn. Set on the border between North and mainland Ireland and featuring mismatched detectives who somehow create a formidable crime-fighting partnership, think of it like True Detective with an Irish twist.
Created and written by Cold Feet writer John Forte and starring Line of Duty’s Amy De Bhrún, the premise is a particularly strong one. The series introduces us to prim Northern Irish detective inspector Philip Boyd (Eoin Macken) and his sweary counterpart from the Republic of Ireland Aoife Regan (De Bhrún), who find themselves partnered up on a brutal murder case. Forced to put their differences aside, they collaborate to solve a crime that straddles the border keeping them apart.
While we count down the days for Borderline to be released on ITVX, here’s everything you need to know about it, including the cast, plot, and how to watch it.
What is Borderline about?
As we mentioned, the six-part series follows an (at first glance) ill-suited detective pair working across the Irish border to solve a murder mystery. Straitlaced detective inspector Philip Boyd (Eoin Macken) of North Ireland finds himself working alongside his foul-mouthed Republic of Ireland counterpart, detective inspector Aoife Regan (Amy De Bhrún). The pair are opposites with clashing personalities and backgrounds, but although neither of them are happy about the partnership, the two must put their personal and professional differences aside to solve the brutal cases of victims along the border.
