Polly Waterford is recovering from a toxic relationship. Unable to afford her flat, she has to move miles away from everyone, to a sleepy little seaside resort in Cornwall, where she lives alone above an abandoned shop. And so Polly takes out her frustrations on her favourite hobby: making bread. But what was previously a weekend diversion suddenly becomes far more important as she pours her emotions into kneading and pounding the dough, and each loaf becomes better and better ... And people start to hear about it.
