Set in a crumbling cop shop on the wrong side of Manchester "No Offence" follows a group of police on the front line, wondering what they did to end up here - in this force, on this side of town. Led by Dl Viv Deering (Joanna Scanlan) - the station's sharp, funny (peculiar) and hard-as-they-come boss, drug labs, arsonists, neo-Nazis and notorious murderers are all in a day's work for this close-knit team. But when a particularly twisted serial killer emerges, it leaves even the most hardened of these seasoned coppers reeling. Flanked by her right-hand women, DC Dinah Kowalski (Elaine Cassidy) - smart but impetuous and DS Joy Freers (Alexandra Roach) - buttoned up so tight she might pop but she's nobody's mug, Deering and her team must crack this case by whatever unconventional means possible. Will Mellor, Paul Ritter and Colin Salmon join them in the mix of tough and big-hearted bobbies who go above and beyond to bring down the criminal rabble in this ugly corner of town.
