In the somber aftermath of postwar Britain, a mysterious letter from the once steadfast housekeeper, Miss Kenton (Emma Thompson), triggers a transformative journey for Stevens (Anthony Hopkins), the meticulous butler of Darlington Hall. After the death of their former employer, Earl Darlington, the estate now falls under the ownership of retired US Congressman Jack Lewis, its luster dimmed by the Earl’s controversial connections to Nazi Germany.

As Stevens embarks on a quest to reconnect with Miss Kenton in the West Country, flashbacks to the 1930s reveal the complexities of their relationship. When Miss Kenton first joined Darlington Hall, Stevens’ unyielding dedication to service frequently clashed with her warmth and spirited nature. He faced personal turmoil as he grappled with his father’s deteriorating health while simultaneously managing a household entwined with political turmoil.

Stevens epitomized professionalism, even in the face of grave circumstances, such as when he dismissed two newly appointed German-Jewish maids under pressure from the estate’s political environment. This moment brought Stevens face-to-face with the stark realities of Nazi racial laws. Even as tensions brewed beneath the surface, there were glimpses of warmth exchanged between Stevens and Kenton, whose feelings began to surface through subtle gestures, despite Stevens remaining emotionally barricaded.

The pages of his life turned further when Reginald Cardinal, the godson of Lord Darlington, visited as a meeting between British Prime Minister Neville Chamberlain and German Ambassador Joachim von Ribbentrop loomed. Stevens found himself torn as he observed the Earl chasing appeasement, ultimately clinging to his role rather than confronting the difficult reality of his employer’s actions.

With her relationship with Tom Benn evolving, Miss Kenton confronted Stevens with a pivotal choice: acknowledge her decision to marry or risk losing her forever. Stevens’ tepid response of mere congratulations led Kenton to ultimately leave Darlington Hall, teetering on the brink of war—a heartbreaking end to their intricate connection.

In 1958, as Stevens sought Kenton in her boarding house, his journey mirrored a quest for identity, resulting in a revealing dialogue with the perceptive Doctor Carlisle that touched on Lord Darlington’s controversial past. While he wrestled with loyalty and regret, Stevens also admitted to being charmed by the very ideologies he later criticized.

Upon their reunion, nostalgia pervaded the air as they reminisced about a shared history laced with ambition and loss. Kenton’s yearning for renewal illuminated the unfinished business of their past, even as Stevens continued to reflect on what might have been. Their parting served as a stark reminder of the unfulfilled desires that lingered in the air, thick with unspoken emotions.

As Stevens returned to Darlington Hall, weighed down by memories and the inevitable passage of time, the sprawling landscape unfolded around him. Together with Lewis, the act of releasing a pigeon into the sky symbolized his longing for freedom from the chains of the past. The camera gradually withdrew from the once-grand estate, painting a poignant picture of lost dreams and fading echoes, enveloped by the verdant hills that bore witness to their intertwined fates.
