From their first meeting at the student union over a decade ago, Jim and Alison successfully navigated their way through first dates, meeting parents, moving in together and more! Then they split up and divided their worldly goods (including a sofa, a cat and their flat) into his 'n' hers. Now, three years on and with new lives and new loves, they couldn't be happier. Until a chance encounter throws them back together, and causes them to embark on a journey through their past to ask themselves the big question: where did it all go wrong, and is it too late to put it all right?
