Laurence Olivier provides the opening narration over a moving aerial shot of 1919 London, setting a quiet, hopeful tone as the city begins to rebuild after four long years of war. “After four long years of war, the men are coming home. Hundreds and hundreds of houses are becoming homes once more.”
Set in South London, the film centers on the Gibbons family—Frank Gibbons [Robert Newton], his wife Ethel Gibbons [Celia Johnson], and their children Reg Gibbons [John Blythe], Vi Gibbons [Eileen Erskine], and Queenie Gibbons [Kay Walsh]—as well as Frank's widowed sister Sylvia [Alison Leggatt] and Ethel's mother. Frank, a warm and practical man, lands a job with a travel agency that arranges tours of the Western Front, a choice that both reflects and shapes the family's postwar adjustments. The bustling city around them slowly adopts new entertainments and technologies, from the Wembley Empire Exhibition in 1924 to the purchase of a crystal radio around Christmas 1925, moments that symbolize a growing sense of modern life and shared optimism.
As the decade advances, the country faces its own tensions. The General Strike of 1926 finds Frank and Bob Mitchell [Stanley Holloway], a friend from his army days, volunteering as a bus driver and conductor, a small but telling sign of ordinary citizens stepping into responsibility during uncertain times. The events ripple through the family: Reg sustains an injury in a brawl, Vi blames her socialist boyfriend, Sam Leadbitter [Guy Verney], who had brought Reg into the fray, and the couple eventually marry despite the upheaval. Queenie, who moves with the family’s orbit, wins a Charleston contest in 1928, turning a moment of simple grace into another thread in the tapestry of their lives. The year 1929 brings the onset of sound film as Sam and Vi attend one of the new talking pictures, The Broadway Melody, and the wider world begins to echo of political change as news of the Nazi rise in Germany starts filtering into newspapers.
Reg’s marriage to Phyl—Phyllis Blake [Betty Fleetwood]—adds another layer to the family’s story, hinting at the compromises and tensions within close-knit households. Bob’s son Billy Mitchell [John Mills], who has joined the Royal Navy, becomes romantically entangled with Queenie. He asks her about other suitors, and she initially says nothing, prompting him to guess that the other man is married. The dynamics inside the house grow more complicated as the era’s shadows lengthen.
One night, after a drunken regimental reunion in 1931, Bob expresses his optimistic faith in the League of Nations, while Frank grows anxious about the Japanese invasion of Manchuria. They try to keep quiet, but their concerns wake Ethel, who sends Bob home and sends Frank to bed. A discovered letter reveals that Queenie has run off with the married man, a blow that Ethel receives with a stubborn, painful reserve and a vow never to forgive.
As years pass, the family endures sorrow: Reg and Phyl die in a car crash, and Ethel’s mother dies of pneumonia after influenza, while Aunt Sylvia discovers spiritualism. In Hyde Park, Frank and Ethel briefly witness a disturbing moment as a member of the British Union of Fascists tries to stir anti-Semitic sentiment among listeners. The political climate shifts with the 1935 general election, and Stanley Baldwin’s government comes to power.
In January 1936, King George V dies, and Frank and Ethel join the crowds filing past his coffin; less than a year later, King Edward VIII abdicates the throne, signaling another upheaval in the country’s story. By 1938, Neville Chamberlain returns from Munich, triumphantly announcing “peace in our time” to a cheering crowd outside 10 Downing Street, a moment Frank greets with disgust at what he fears lies ahead. On leave from the navy, Billy visits with news of Queenie, who—after being abandoned by her lover—had already opened a tearoom in France to make ends meet and regrets leaving home. Billy reveals that he has married Queenie and brought her back to London, and Ethel offers forgiveness.
With a new war looming despite emerging agreements, Queenie leaves her baby with her parents and sails to join her husband in Singapore. The family space shifts once more as Frank and Ethel move to a flat with Billy and Queenie’s son. The story closes on a contemplative note, with a long tracking shot of 1939 London that suggests both the resilience and fragility of a generation waiting for what comes next.
