Two couples, best friends for half a lifetime, move in together. What could possibly go wrong? Harriet and Mark have it all: successful careers, a lovely house in a leafy London suburb, twin boys on the cusp of leaving home. Yvette and Gary share a smaller place with their two daughters in a shabbier part of the same borough. But when the stars align for a collective move north, it means a fresh start for them all. For Mark, it's a chance to escape the rat race; for Harriet, a distraction from her unfulfilled dream of a late third child. Gary has decided to reboot the Madchester band that made him famous, while Yvette hopes it will give her daughters what she never had herself. But as the reality of their new living arrangements slowly sinks in, the four friends face their own mid-life crises, and the dream becomes a nightmare...
