Johnny Nyle is a young crooner who spends a day filming a television performance of a song from the musical “Meet Me in St Louis.” After the shoot, as fans wait to catch a glimpse, a young woman steps forward to confirm his identity and hands him a summons that hints at trouble brewing offstage.
Adam Calhorn Shaw runs a bustling legal office, where he is still haunted by memories of his time in the navy. He’s juggling his political ambitions with the pressures of a personal life that feels increasingly complicated. His secretary, Miss Seely, keeps the day moving, but Adam is preoccupied, both by a previously promised appointment and the nagging sense that someone is pulling strings behind his back. Johnny, determined to get a word with his former lieutenant, leaves a message and heads back into the world of publicity and performance.
In the wings of the campaign, Adam is surrounded by a trio of influential men who want to steer his rise to Congress. Mr Grenville, a seasoned family friend; Mr Griswalde, Adam’s law firm partner; and Mr Tremaine, the campaign manager, all weigh in as the political clock ticks louder. Yet Adam is not always cooperative; he is distracted by the seemingly trivial, like the death of five peach trees he had purchased from a nursery, a strange omen that keeps intruding on his thoughts.
When Adam finally makes it to the nursery to voice his complaint, he meets the effervescent and somewhat eccentric Athena Mulvain. She offers unsolicited but spirited advice on reviving the peach trees, and, with a mischievous spark, she begins talking about numerology and compatibility, which unsettles Adam enough to end the encounter on a tense note. Later, he recounts this odd meeting to his fiancée, Beth Hallson, a polished society woman, who seems unimpressed by Athena’s carefree energy.
The next encounter with Athena is even more provocative. She shocks [Beth] by speaking to her in Japanese and then appears again at Adam’s home to “mulch” the peach trees, bringing a playful, musical mood into the house. Athena’s charm comes to life in a lively number called Vocalise, a performance that makes it clear she is not merely an uninvited guest in Adam’s life. She steals a moment with Adam and seals it with a kiss, before stepping out and crossing paths with Johnny, who flirts with her in turn. Athena makes it clear that, in her view, Adam and she are meant to be, and she even muses about whether Johnny could be a match for one of her six sisters, including Minerva Mulvain.
Minerva Mulvain, a sharp-eyed sister with her own reservations about public image and morality, is introduced when Johnny drops off his documents at Adam’s letterbox and ends up at the Mulvain family health food store. Minerva is wary of Johnny’s promotion of alcohol and meat products, and though she is skeptical of his public persona, she and Johnny begin to share a moment in a duet called “Imagine.” The flirtation is not simple: Minerva has a cool, teasing wit, and she immediately recognizes Johnny as someone who could threaten or help her sister Athena’s plans for love, depending on how the stars align.
As the days unfold, Athena returns to Adam’s life with renewed fervor. Adam’s breakfast conversation with Beth contrasts with Athena’s light, free-spirited approach, and Adam promises to tell Athena that there is no romantic future between them. Yet Athena disappears again, leaving Adam to search for her through Miss Seely and the wider social circle. The tension builds as the two families—Athena’s lively Mulvains and Adam’s more conservative world—gradually collide.
That evening, Adam is invited to dinner at the Mulvain house, where the sisters perform a grand rendition of Vocalise, this time reimagined as Harmonise. The meal becomes a stage for competing expectations: Adam’s desire for a clear break with the past, Athena’s insistence on following love, and Grandpa Ulysses Mulvain’s (the formidable Grandpa Ulysses Mulvain) stubborn pride, which has built up around the family’s Mr. Universe ambitions. The dinner is lively, and for a moment it seems that harmony might prevail, but Adam’s hesitation and Beth’s lingering presence complicate the scene.
The next day, the atmosphere thickens as politics, love, and family history collide in dramatic fashion. The Mulvains reveal a larger world of bodybuilders—led by Grandpa’s training and featuring Ed Perkins and Bill Nichols—who come to symbolize a philosophy of strength and discipline. The final moment of the day occurs during a televised Mr. Universe final, where Ed and another contestant pose to the tango-inflected music of “Jalousie.” A quick loom of humiliation follows when Adam’s judo-throwing move on a rival is captured on camera, a moment that threatens to derail his political career.
Back at the Mulvain house, Grandpa’s hope that Ed will marry Athena to produce “perfect children” is aired, and the tension between personal happiness and public duty peaks. Johnny learns of Grandpa’s plan and decides to support Athena in choosing love over politics. A pivotal scene follows when Johnny and Minerva share a line of understanding: “Love can change the stars,” a sentiment that is echoed by Athena’s insistence that people matter more than vegetables or appearances.
As the story moves toward its resolution, Adam confronts Grandpa about the hypocrisy of placing ideology above people. He argues that compassion and human connection should guide choices, not the politics of purity or the optics of public service. The morning after, Athena meets Adam with a simple invitation to share a meal—ham and eggs—emphasizing that people matter more than any abstract dietary creed. The Mulvain family then rallies around the idea of unity and acceptance.
In the film’s closing moments, Athena returns to perform the once-again triumphant Harmonise, and the camera pulls back to reveal the ensemble—[Athena Mulvain], [Minerva Mulvain], [Grandpa Ulysses Mulvain], Niobe Mulvain, and their friends and allies—singing together on the floor in a warm, communal celebration of love and family. The screen lingers on the sense that, in this quirky, music-filled world, happiness is found not in a spotless blueprint but in the messy, joyful harmonies of real people choosing one another.
> Love can change the stars
The end leaves audiences with a hopeful chorus: the cast’s voices blend into a final communal refrain as they share fruit and laughter, a Mulvain-style feast that seals the message that people—and their connections—outweigh every obstacle.
