In 1910, Paris faces a dramatic flood of the River Seine that reshapes daily life for thousands. Boats become the way across town, wooden walkways crisscross the waterlogged streets, and the city’s landmarks loom over a waterline that reaches awe-inspiring heights, even brushing the foot of the Eiffel Tower. Against this storm of water and worry, a quiet, hopeful story unfolds.
Emile is a shy projectionist with a strong love for film and a secret crush on his coworker at the cinema, Maud. When the belt that powers his projector snaps, he improvises with his own belt to finish the movie for the audience, a tiny act of resilience that hints at his deeper courage. His close friend, the exuberant inventor and delivery driver Raoul, whisks him away in a peculiar vehicle named “Catherine,” powered by sunflower oil, to fetch a replacement belt and a new camera. Their trip is a mix of comic danger and earnest ambition: a would-be thief nearly steals the moment, only to be thwarted when he collides with Catherine.
On Raoul’s advice, Emile writes a letter to Maud expressing his feelings, a gesture that becomes as much about finding a voice as about revealing the man behind the projection booth. At the same time, Lucille, Raoul’s childhood friend and a cabaret singer at L’Oiseau Rare, captivates Paris with song, while her formidable aunt, Madame Carlotta, schemes to marry her to the wealthy and calculating Le préfet Maynott. Maynott’s political ambitions are slipping, and his appetite for influence tempts him to manipulate Lucille’s world for applause and power, all while he pursues his own romantic gambit with her.
During a visit to the Botanical Gardens, guarded by a clever monkey named Charles in the professor’s absence, Raoul fiddles with an improvised mix of lab experiments: an “Atomize-a-Tune” formula that temporarily gives Charles the voice of an opera star, and a volatile “super fertilizer” that makes a sunflower seed sprout into a colossal bloom. The chemistry of water, wind, and wonder misfires in a spectacular explosion. From the blast, Emile reports catching a glimpse of a monstrous creature—seven feet tall, with red eyes, four arms, and spikes across its body—a sight that will later appear in newspapers and on the front pages of Paris.
The incident becomes a matter of public interest, with an investigation led by Le préfet Maynott through his loyal aide Pâté, even as the public’s appetite for sensational spectacle grows. Meanwhile, Emile and Raoul develop the film they shot in the botanical lab, and what they see on the reels confirms the monstrous sighting. Lucille, seeking a new musician for her act, mentors her own show by discovering a gifted singer in an unexpected form: the creature from the laboratory, when not terrifying, reveals a beautiful, almost human singing voice.
The creature, named Francoeur in Lucille’s orbit, escapes suspicion by dazzling audiences with song. Albert, a waiter who briefly crosses paths with the creature, stumbles upon the truth and, terrified, alerts the authorities. Lucille’s compassion ultimately sees past fear, and she welcomes Francoeur into her world as a musician rather than a monster. The police, led by Maynott, close in, but the trio—Emile, Raoul, and Francoeur—flee through a city that is as flooded as their own lives, culminating in a dramatic confrontation atop the Eiffel Tower.
A gunshot and a sudden disappearance lead the crowd to believe Francoeur is dead, and Maynott is momentarily empowered by the crisis. Yet Emile and Maud find each other, and the real truth emerges when the Professor returns and works with them to restore Francoeur to human size. The city’s stage is set for a brighter future: Francoeur receives second billing on Lucille’s posters, and Lucille and Raoul share a quiet, hopeful kiss as the narrative closes on a note of friendship, music, and rediscovered love.
In a playful coda, the cast—Emile, Maud, Lucille, Raoul, Francoeur, Charles the monkey, Carlotta, and Pâté—sprouts a final burst of life by scattering super-fertilized sunflower seeds to drain the flooded Seine, a whimsical gesture that nods to science, resilience, and communal effort. A second post-credits scene leaves Le préfet Maynott still in custody alongside Albert and the earlier thief, enduring the duo’s famously awful singing as a petty, humorous punishment.
The film blends danger and delight with a gentle, cinematic charm. It celebrates creativity and friendship in a time of crisis, inviting audiences to consider how art, courage, and collaboration can transform chaos into beauty, even when the world seems overwhelmed by water and fear.
