London, 1946. Juliet (Lily James, Cinderella), a charismatic and free-spirited writer, receives a letter from a member of a mysterious literary club started in Nazi-occupied Guernsey. Her curiosity piqued, Juliet decides to visit the island. There she meets the delightfully eccentric members of the Guernsey Literary and Potato Peel Pie Society, including Dawsey (Michiel Huisman, Game of Thrones), the rugged and intriguing famer who wrote her the letter. As the secrets from their wartime past unfold, Juliet’s growing attachment to the island, the book club and her affection for Dawsey will change the course of her life forever.
