Three couples. One therapist's couch ...

Alice and Niall used to be lovers, best friends and parents, in that order. Now they're no longer on the same page or even reading from the same book.

Ann thought when she and Ken retired, it would be their second spring. Instead, it feels more like an icy winter.

Orla is falling in love with boyfriend Paul, but her complicated past makes her unsure if she can ever be intimate with anyone.

Three couples find themselves telling a stranger about the most private part of their lives - their hopes, their disappointments, their awkward realisations.

Can they learn to be honest with each other? And what life-changing decisions will be made when they do?
