Cousins Scarlett Parker and Vivian Tremont's fashionable London hat shop, Mim's Whims, is visited by a new customer bearing an old hat box. Ariana Jackson is getting married and wants to restore her mother's bridal hat and veil for the occasion. The elegant item was made by Scarlett and Vivian's grandmother over 30 years ago, so Viv is delighted to take the job. When Scarlett goes to Ariana's office to consult about the restoration cost, she finds her outside, standing over her boss's dead body.

Scarlett Parker and her British cousin, Vivian Tremont, are hard at work at Mim's Whims-their ladies' hat shop on London's chic Portobello Road-to create hats for an Alice in Wonderland - themed afternoon tea, a fund-raiser for a local children's hospital. It seems like a wonderfully whimsical way to pass the hat, and Scarlett and Viv are delighted to outfit the Grisby family, the hosts who are hoping to raise enough money to name a new hospital wing after their patriarch.

London milliner Vivian Tremont and her American cousin and partner, Scarlett Parker, tip their caps to their beloved shop on Portobello Road in Notting Hill and set off for Paris, where Viv can't wait to teach a hat-making class. But she has another reason to travel to the City of Light: to find the man she impulsively eloped with years ago and have their marriage annulled. William Graham is not only handsome and charming, but he also has a glamorous job as an insurance investigator who works with priceless pieces of art.

Not only is Scarlett Parker's love life in the loo - as her British cousin Vivian Tremont would say - it's also gone viral with an embarrassing video. So when Viv suggests Scarlett leave Florida to lay low in London, she hops on the next plane across the pond. Viv is the proprietor of Mims's Whims, a ladies' hat shop on Portobello Road bequeathed to both cousins by their beloved grandmother, and she wants Scarlett to finally join her in the millinery business. But a few surprises await Scarlett in London.

For Scarlett Parker, part of the fun of living in London is celebrating the British holidays, and she's excited to share her first Bonfire Night with her cousin Vivian Tremont. Invited to a posh party by their friend Harrison Wentworth, Scarlett and Viv decide to promote their hat shop, Mim's Whims, by donning a few of their more outrageous creations. The hats prove to be quite the conversation starters as the girls mix and mingle with the guests - never suspecting that one of them is a killer.
