When Ros steps off a plane after three years away, she's in need of a new job, a new flat and a new start. But her friends have moved on, her parents only have eyes for each other, and her bedroom has been moved into the garden shed. Suddenly, Ros has a bad case of nostalgia for the way things were. Then her phone begins to ping with messages from her old life. Including one number she thought she'd erased forever: the man who broke her heart. Sometimes we'd all like the chance to see what we've been missing.
