Grace has been best friends with Ella and Flick since university. The late-night chats, shared heartaches and good times have created a bond that has stood the test of time. Now in their thirties, Grace is always a bit disappointed about how little time they get to spend together, so when Ella invites them all to stay for a week in her cottage in South Wales, Grace jumps at the chance to see her old friends. She also hopes that the change in pace will help her reconnect with her husband, Harry. Unfortunately for her, Harry isn't as enamoured with Cwtch Cottage as she is.
