Meet Harold Fry, recently retired. He lives in a small English village with his wife, Maureen, who seems irritated by almost everything he does. Little differentiates one day from the next. Then one morning the mail arrives, and within the stack is a letter addressed to Harold from a woman he hasn't seen or heard from in twenty years. Queenie Hennessy is in hospice and is writing to say goodbye. Harold pens a quick reply and heads to the corner mailbox. But then Harold has a chance encounter, one that convinces him that he absolutely must deliver his message to Queenie in person. Harold Fry is determined to walk six hundred miles from Kingsbridge to the hospice in Berwick-upon-Tweed because, he believes, as long as he walks, Queenie Hennessy will live. Along the way he meets one fascinating character after another, each of whom unlocks his long-dormant spirit and sense of promise. Memories of his first dance with Maureen, his wedding day, his joy in fatherhood, come rushing back to him -- allowing him to also reconcile the losses and the regrets. As for Maureen, she finds herself missing Harold for the first time in years. And then there is the unfinished business with Queenie Hennessy.
