What Happens in The Only One: Full Plot Summary

The whole story of The Only One (2006) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Lucien Nand Buyl is a stubborn man in his eighties whose routine becomes a daily clash when he moves into his daughter Gerda’s house after his wife’s death. The transition throws him into a small world of shared living with other residents, and his uncompromising way of life routinely disrupts the rhythm of the home. He resists many of Gerda’s requests, stubbornly pushing back against authority and refusing to cede control over his own life.

After yet another incident, Gerda nears her limit and contemplates placing him in a rest home. To her relief, Lucien abruptly announces that he won’t stay and will return to his own house, insisting that his “new girlfriend” will also come along. Gerda sharpens her budget and worries about the money she had earmarked for a deluxe campervan to visit Spain, fearing this plot is more about fuel for manipulation than genuine affection.

Lucien later confides in his granddaughter Julie that he does not actually have a new girlfriend yet. In the household, Mathilde, the wife of his best friend Felix, becomes a fixture who will handle housekeeping. Mathilde Viviane de Muynck is drawn into the older man’s life in ways that reveal past secrets: the two had already been involved when Lucien’s wife was still alive, and they once promised each other eternal love, though they felt compelled to keep it secret until their respective partners had passed away.

Living on his own proves tougher than Lucien anticipated. He feels the absence of Mathilde when she’s away, and only Julie’s visits bring warmth. When Julie announces she will leave for France to study, the house grows quieter and the days expand with a kind of lonely restlessness.

A sharp turn arrives with a new neighbor, Sylvia Marijke Pinoy, a woman in her mid-to-late forties who piques Lucien’s curiosity. Sylvia brings energy, instruction, and a spark of youth back into his life. She teaches him how to manage the housekeeping routine and even offers computer lessons, reviving his interest in daily life and independence. Yet Gerda and Mathilde remain wary of Sylvia, questioning the motives of this unfamiliar intruder in their family dynamic.

As the friendship between Lucien and Sylvia grows, a delicate balance forms—one that promises renewed companionship without abandoning the responsibilities of his family. But the film turns on a decisive choice: Lucien eventually steps back from this budding relationship, choosing to prioritize his family’s stability and the obligations he feels toward them, even if it means letting go of the possible happiness Sylvia represented.

Throughout, the story deftly explores aging, autonomy, and the tension between living independently and belonging to a family. It tracks how memories of love, secrecy, and guilt shape present choices, and it follows Lucien as he navigates the rough terrain of duty, desire, and the fear that change might undermine the careful, fragile peace he has built.

Why does Lucien claim to have a new girlfriend when he doesn't?

Q2

What was the secret between Lucien and Mathilde?

Q3

Why does Lucien end his relationship with Sylvia to stay with his family?

Lucien chooses family duty over personal happiness because he recognizes that his relationship with Sylvia threatens the family's financial stability and peace. Gerda has specific plans for money that would be disrupted by Lucien's independent living arrangements. He prioritizes maintaining harmony and ensuring his daughter's plans remain intact, even sacrificing the renewed vitality Sylvia brought to his life.

Q4

Q5

What does Sylvia teach Lucien that changes his daily life?

Sylvia teaches Lucien practical household management skills and computer lessons, bringing modern relevance back into his life. These lessons represent more than just skills, they restore Lucien's sense of competence and independence.

Q6

Why does Lucien find living alone difficult despite wanting independence?

Living alone proves harder than Lucien expected because he loses the daily social contact and structure that Gerda's household provided.

His granddaughter Julie's visits become his primary source of warmth, making her announcement that she will leave for France to study particularly painful.

Why does Julie leave for France and how does it affect Lucien?

Julie leaves for France to study, representing the next generation's departure from Lucien's life.

Julie had been one of the few bright spots in his difficult transition, making her absence particularly meaningful.

Q8

Why does Gerda consider placing Lucien in a rest home?

Gerda considers a rest home after repeated clashes with her father, who refuses to adapt to household rules or cede any control over his own life. The cumulative tension from his stubborn behavior and resistance to her authority pushes her to this breaking point. The option represents her struggle between filial duty and practical caregiving limits.

Q9

Why does Mathilde become the one to manage Lucien's housekeeping?

Mathilde, the wife of Lucien's best friend Felix, takes on the housekeeping role because of their secret past relationship. Their long-standing affair gives her a unique position in Lucien's life and explains why she is the one who enters his household after his wife's death. This arrangement fulfills both practical needs and their unresolved romantic history.

Q10

What makes Sylvia different from other neighbors in Lucien's life?

Sylvia, a woman in her mid-forties who moves in next door, differs from other characters because she brings renewed vitality and youth to Lucien's world. Unlike his family relationships dominated by duty and obligation, her connection offers genuine companionship and growth. She challenges his routines while respecting his independence, creating a dynamic that feels like a new chapter rather than an obligation.

Foreshadowing: Sylvia's arrival directly leads to Lucien's period of renewal before his final choice.
