Cheese shop owner Charlotte Bessette's life is quieter than ever with her fiance away and her cousin Matthew and his children out of the house. But before she can sit back and enjoy a glass of chardonnay, Matthew asks her to play host to Noelle Adams, a bright sommelier in town to help grow business for the local winery. Noelle is affable, if somewhat troubled, but Charlotte doesn't pry into her secretive houseguest's problems, until Noelle turns up dead.
