In a house in Manchester divided into four flats, we are introduced to four interweaving stories about love, parenthood, loss and self-discovery. Gail bumps into an old friend who makes a startling observation about Gail's marriage.

Three weeks after the events of episode one, the neighbours try to carry on as normal, but life gets in the way. Each has a choice to make: will they stick to old ways, or will they take a step into the unknown?

David investigates Kelly's past; Hannah is drawn to Andy; Gail confronts Henry with her feelings; Belle's ex-husband comes back into the picture.

Henry grapples with the consequences of Gail's decision, Liam throws a tense dinner party, David and Saira start a new chapter, and Neil makes Belle an unexpected offer.

The neighbours remain trapped in situations of their own making. Can they escape?

Hannah's wedding day arrives and all of our characters make their final choices about how to move forward with their lives.
