Self-appointed queen of her English village, Mrs. Braithwaite finds herself dethroned following her husband's divorce petition. Never deterred, the threat of a family secret being revealed sets her hot-foot to London to find the only person she has left—her clever daughter Betty. But when she arrives, Betty's landlord, the timid Mr. Norris, informs her that Betty hasn't been home in days. Storming into the London Blitz, Mrs. Braithwaite drags the reluctant Mr. Norris along as an unwitting sidekick as they piece together Betty's chaotic life, and the village matriarch is forced to rethink her old-fashioned notions of status, class, and reputation.
