Follow the lives and woes of the residents of a Manchester house divided into four different flats. Gemma Foster’s neighbour, Emma, now goes by the name of Belle, looking to start a new life. Three other interconnected stories tell a tale of love, loss, birth, death, the ordinary, the extraordinary, and everything in between.

Keeping these streets clean is a Herculean task, enough to demoralize even the keenest rookie – but there’s a reason why this hotchpotch of committed cops are on this force, on this side of town. Drug labs, arsonists, neo-Nazis and notorious murderers are all in a day’s work for this close-knit team, led by the dizzyingly capable but unquestionably unhinged DI Vivienne Deering. But when a particularly twisted serial killer emerges it leaves even the most hardened of these seasoned coppers reeling.
