When Mona Ramsey married Lord Teddy Roughton to secure his visa, allowing him to remain in San Francisco to fulfill his wildest dreams, she never imagined she would, by age 48, be the sole owner of Easley House, Teddy's grand, romantic country manor in the UK. She also didn't imagine that she'd need to open the manor's doors to paying guests to afford the electric bill and repair the leaking roof. Yet somehow she and her young friend Wilfred, whom guests assume is serving as Easley's charming-but-clumsy butler, and the loopy old gardener Mr. Hargis, are making it work. This delicate equilibrium is upended when Americans Rhonda and Ernie Blaylock arrive for a weekend vacation at Easley, and Wilfred stumbles onto their terrible secret. Now, instead of being able to focus on the imminent arrival of her old friend Michael Tolliver and beloved parent Anna Madrigal, Mona will need to focus all of her considerable charm, willpower, and wiles, and the help of Wilfred and Mona's girlfriend Poppy, the town's postmistress and local calligraphy whiz, to set things right before the Midsummer ceremony when the whole town will descend on Easley's historic grounds.
