Soho, London, 1958. Three women. One boarding house. A secret that could shatter everything.

One wet afternoon in 1954, after a whirlwind romance, Edie West married Frank Budd in a South London registry office. With a spool of blue ribbon tied around her bouquet, she promised to love, honour, and obey him - for better, or worse.

Two years later, Edie arrives alone at 73 Dove Street, a West London boarding house run by the formidable Phyllis Collier: exhausted, nervous, carrying nothing but a cardboard suitcase. Phyllis' other lodger, Tommie, keeps herself to herself. But when Tommie discovers a secret from Edie and Frank's marriage, she's faced with a choice. Will she turn the other way? Or help set Edie free?
