The Guernsey Literary and Potato Peel Pie Society

In 1941, in the midst of German occupation in Guernsey, four friends find themselves in a precarious situation after violating curfew. To avoid arrest, they quickly fabricate a story about attending a book club meeting, which they whimsically name the 'Guernsey Literary and Potato Peel Pie Society.'

By January 1946, author Juliet Ashton is actively promoting her latest literary work, written under the pseudonym Izzy Bickerstaff. With the support of her publisher, Sidney Stark, she writes articles for The Times Literary Supplement, delving into the enriching influence of literature.

Juliet receives a poignant letter from Dawsey Adams, a Guernsey resident who possesses her edition of Charles Lamb's 'Essays of Elia.' His inquiry about a bookshop in England is coupled with a mention of his participation in a weekly book club, igniting Juliet's curiosity about this unique gathering.

Intrigued by the idea of the book club, Juliet decides to visit Guernsey despite her boyfriend Sidney's reservations. Before her departure, Mark Reynolds proposes to her, and she accepts, unaware of the transformative journey ahead.

Upon her arrival in Guernsey, Juliet is warmly welcomed as a special guest at a society meeting. The members, including Dawsey and Amelia, are charmed by her presence, but they inform her that Elizabeth, the founding member, is currently absent.

Juliet, rather than returning home as initially planned, opts to extend her stay under the guise of researching for a new article about the German occupation. During her time in Guernsey, she begins uncovering the mysterious past of Elizabeth, who was arrested during the war.

Juliet reaches out to Mark, who is serving in the armed forces, for help in locating Elizabeth. Through her conversations, she learns about Elizabeth's troubled past and her connection with the German soldiers during their occupation, deepening her investigation.

In a revealing moment, Dawsey shares that he is not Kit's biological father, but that Kit's real father was a German doctor named Christian Hellmann. This heart-wrenching story highlights the complexities of love during wartime and sheds light on Elizabeth's entangled past.

Mark arrives in Guernsey with distressing news for the society. He reveals that Elizabeth was taken to Ravensbrück concentration camp and tragically died while attempting to save another inmate, casting a shadow over the community's hope for her return.

After returning to London, Juliet finds it challenging to reintegrate into her former life. Her relationship with Mark deteriorates as the impact of her experiences in Guernsey weighs heavily on her, ultimately leading to the end of their engagement.

Juliet channels her emotions and experiences into a manuscript about the Guernsey Literary and Potato Peel Pie Society. Once completed, she shares it with Sidney and sends a copy to the society members, hoping to keep the spirit of their community alive.

In a poignant moment, Dawsey reads Juliet's heartfelt letter to the group, which reveals her decision to end her engagement. As she prepares to return to Guernsey, their paths cross on the ferry, leading to a touching reunion where both express their desire to be together.

Time progresses, and we see Dawsey reading to Kit from 'Tales from Shakespeare,' with Juliet by his side. Both wear wedding rings, symbolizing their commitment and the new life they are building together against the backdrop of their shared history.

The film concludes with the promise of the society's next meeting happening off-screen, featuring Sidney among the members. They engage in joyous literary discussions, celebrating the bonds they have forged and the stories that continue to unfold.
