When Ros steps off a plane after four years away she's in need of a job, a flat and a phone that actually works. And, possibly, her old life back. Because everyone at home has moved on, she's sleeping in a converted shed and she's got a bad case of nostalgia for the way things were. Then her new phone begins to ping with messages from people she thought were deleted for good. Including one number she knows off by heart: her ex's. A hilarious, relatable, romantic comedy.
