In 1843, despite the fact that Dickens is a successful writer, the failure of his latest book puts his career at a crossroads, until the moment when, struggling with inspiration and confronting reality with his childhood memories, a new character is born in the depths of his troubled mind; an old, lonely, embittered man, so vivid, so human, that a whole world grows around him, a story so inspiring that changed the meaning of Christmas forever.
Based on the bestselling novel, Lily James plays free-spirited writer Juliet Ashton, who forms a life-changing bond with the eccentric Guernsey Literary and Potato Peel Pie Society, when she decides to write about the book club they formed during the occupation of Guernsey during WWII.
