The film opens in an upscale apartment in a metropolitan city where Param, a young man born to wealth, moves through his day with the casual confidence of someone accustomed to privilege. He spends his time scanning startup pitches, transferring capital, and testing new technologies with a taste for novelty. Param's father, a pragmatic businessman, watches these investments with a mixture of pride and skepticism; he respects his son's acumen but doubts the wisdom of betting family money on every unproven idea. To confront that doubt, Param seeks a wager: he promises to prove that one of the new-generation matchmaking platforms is superior to traditional judgement by family and custom.

Param discovers an application called Soulmates, promoted for using sophisticated algorithms to locate a person's most compatible partner, and he decides to use it as a demonstration. He enters his information, watches the app process biometric and behavioral inputs, and waits. When Soulmates returns a match, Param reads the result aloud to his father to add theatricality to the challenge: the app has paired him with Thekkepattu Sundari Damodharan Pillai, an owner of a homestay in a rural part of Kerala. Param's father laughs at the improbability--an urban investor matched with the steward of an ancestral Kerala house--but Param is intent on proving the point and arranges a trip to meet the woman the algorithm names.

Param travels to Kerala. He arrives at the village and follows directions down a narrow lane until he sees the sprawling, timeworn compound of a Tharavad--an ancestral family house--set against a backdrop of coconut trees and a bright sky. The homestay's sign bears the full name: Thekkepattu Sundari Damodharan Pillai. Param rings the bell and enters into a household where daily life follows a rhythm far removed from his city routine.

Sundari meets him at the threshold. She is the woman whose name the app produced: she runs the ancestral home as a homestay and keeps its rituals and routines, managing bookings, cleaning rooms, preparing food, and receiving guests with the practiced ease of someone who has lived in the house all her life. Her uncle, Bhargavan Nair, lives there too. He upholds the family's martial tradition as a practitioner and teacher of Kalari Payattu; he conducts training sessions in the courtyard and keeps an eye on the preservation of the Tharavad's discipline. Sundari and Bhargavan move through the house with complementary roles: she tends to guests and accounts, while he maintains physical training and the cultural continuity of the compound.

Param and Sundari's first conversation is controlled by politeness punctuated by curiosity. Param speaks about the app and his reason for coming; Sundari listens, asks questions about what city life is like, and corrects a few assumptions he makes about rural living. Param notes the ancestral photos on the walls, the brass lamps, the woven mats and the way Sundari manages reservations with a ledger rather than an app. Sundari shows him a guest room, its carved wood and linen carefully laid. Param records details on his phone, both because he wants to prove the match to his father and because he is intrigued by the differences.

Bhargavan Nair watches Param with the calm suspicion of someone tasked with guarding a family's honor. He offers a demonstration of Kalari Payattu: he moves into a sequence of exercises and strikes, the body moving with a slow power that commands the courtyard. He invites Param to try a few basic positions. Param accepts with the exuberance of a man used to quick mastery, but he finds the discipline unfamiliar and difficult. He stumbles through the postures; Bhargavan corrects him briskly. The practice becomes an early point of cultural collision--the urban investor learning to accept instruction from a traditional martial practitioner. Param's clumsy attempts amuse Sundari, who calls out modifications and offers him a drink after the lesson.

In the days that follow, Param immerses himself in the Tharavad's rhythms. He helps Sundari with morning chores, learns to prepare some regional dishes under her direction, and takes notes on the homestay's operations with an economist's eye. He books local excursions for guests and addresses inquiries using his phone. Sundari explains how bookings fluctuate by season, how guests appreciate quiet and authenticity, and how maintaining the house demands constant attention. Param listens and questions; he suggests digital marketing strategies, new amenities, and ways to connect the homestay to city travelers. Sundari reacts with a mixture of amusement and caution. She is protective of the house and its customs and resists ideas that might strip the place of its character.

Param invites Sundari to discuss the Soulmates result; he asks how she feels about an algorithm matching two people. Sundari answers plainly: she believes in the practical work of life--maintaining the house, honoring the family lineage, supporting her uncle--rather than tests introduced by outsiders. She is polite but reserved when Param speaks about love and compatibility as things an app can predict. Their conversation circles around their different assumptions, yet also reveals curiosity. Param admires Sundari's competence and the way she moves through the Tharavad's responsibilities, while Sundari notices his confidence and his eagerness to challenge convention.

When Param contacts his father, he reports on the homestay and sends photos. Param's father responds with a mix of mockery and genuine curiosity; he advises caution but concedes that Param has provided interesting data for his supposed experiment. Param continues to spend time at the Tharavad. He makes pragmatic proposals to improve the homestay's booking system; he also learns to perform small rituals in the house and attends to guests' needs with Sundari's instruction. Sundari increasingly includes him in household tasks: she shows him how to replace an oil lamp's wick, how to fold the traditional mats, and how to bargain with a supplier in the nearby town. Param pays attention to each detail.

Param's presence affects the routine. Guests notice the contrast between his urban manners and Sundari's quiet efficiency. Some are intrigued and ask questions; others prefer the simplicity Sundari offers. Bhargavan watches the interactions; he keeps training in the background and steps forward if Param's actions seem to threaten the house's customs. He warns Param in private about overstepping. "This house survives because of its rules," Bhargavan tells him, and Param nods, acknowledging the lesson. Param's attempts to introduce change meet concrete resistance: when he suggests converting a storage room into a modern lounge, Sundari rejects the idea because it would require altering a carved wooden pillar that carries the family's names. Param withdraws but continues to propose more subtle changes, such as an online calendar configuration that respects the house's timings.

As Param and Sundari spend more time together, small disagreements reveal deeper differences. Param expects immediate, measurable outcomes; Sundari expects deliberation and respect for continuity. Their arguments are precise: Param speaks about metrics--occupancy rates, return guest percentages, potential revenue--while Sundari replies with details about ancestral rituals and the responsibility to preserve family heirlooms. They clash over whether a souvenir shop might attract more urban guests; Sundari fears commodification. When Param suggests a schedule change that shortens the daily puja to accommodate city guests' arrival times, Sundari refuses. Param, unfamiliar with the emotional weight of these daily acts, feels frustrated; Sundari is offended at the idea of modifying rituals for convenience.

Despite these episodes, Param and Sundari find moments of connection. Param helps Sundari repair a leaky section of the roof by standing on the rafters and passing tools; they laugh at the awkwardness as dust falls and a beam creaks. Param listens to stories about the family history that Sundari shares late at night: accounts of ancestors who managed the house through floods and harvest failures, the names inscribed on a ledger, and the way the Tharavad's rooms are given to different generations. Sundari talks about her father and mother in clinical detail--what they taught her about managing accounts and the discipline Bhargavan instilled in her as a child. Param feels his original experiment shift. He is learning the house's particular logic, and he recognizes that compatibility requires more than data.

Bhargavan continues to exercise and to instruct local youths in Kalari. He becomes a reluctant ally when Param defends the house against an unscrupulous developer from the town who tries to acquire land by promising modernization. The developer arrives with brochures and promises of road improvements, and he targets several ancestral properties in the area. Param discovers a conversation in which the developer downplays the Tharavad's value while offering cash that would allow Param's father to claim a quick return on his son's investment. Param and Sundari respond differently: Param views the offer as a financial proposition that must be weighed; Sundari sees the developer's proposal as a threat to the integrity of the house. Param arranges a meeting with the developer to evaluate legal documents, and he uses his financial knowledge to point out deficiencies in the offer. After analyzing the contract and consulting with Bhargavan and local community members, Param negotiates changes that protect the Tharavad from immediate sale. The developer, frustrated, withdraws for the time being. This conflict tests Param's loyalties: he negotiates partly to protect his own reputation after promising his father results, and partly because he has come to appreciate what the Tharavad provides.

As they confront these external pressures, Param and Sundari's private relationship deepens in subtle ways. Param begins to anticipate the house's needs before Sundari asks; he purchases materials for repairs and coordinates a local carpenter. Sundari sees him take responsibility with care rather than imposing blunt solutions. She invites him to sit through a full evening ceremony that honors the ancestor figures whose portraits hang above the inner shrine. Param, who initially regarded such ceremonies as quaint, remains quietly present throughout the ritual, focusing on the gestures, the sequence, and the communal participation. Bhargavan notices his attentiveness and approves with a curt nod.

Param's father grows impatient with the pace of Param's experiment. He arrives in Kerala to see for himself, traveling from the city to the Tharavad with practical questions and guarded expectations. When he meets Sundari and Bhargavan, he observes with the cool scrutiny of a businessman evaluating assets. He asks Sundari about bookings and profitability, and Sundari provides frank answers about the homestay's slow but steady income and its dependence on seasonal tourists. Param's father probes for efficiency improvements but also shows small signs of respect when Bhargavan explains the costs of maintaining the property and the non-monetary value of keeping the Tharavad functional.

Param's father proposes a compromise: he suggests a pilot project to market the homestay to a curated set of city travelers, combine digital outreach with preservation measures, and measure the results over three months. Sundari agrees to a trial provided that the core rituals and the house's structure remain untouched. Param's father signs the agreement with a handshake, and Param records the moment for his own vindication. The app match, which had begun as an experiment to embarrass his father, now takes the form of a practical collaboration. Param feels vindicated; Sundari accepts pragmatic concessions.

As the pilot project proceeds, Param and Sundari collaborate on specific initiatives. Param creates a simple website and curates a gallery that captures the house's distinctiveness. He arranges for a small group of journalists to experience a stay and to write pieces that emphasize the Tharavad's authenticity. Sundari coordinates guest meals, instructs staff on the house's rules, and keeps a ledger of bookings. The occupancy rate improves modestly, and the results provide Param's father with the metrics he values. He expresses approval in a restrained way and returns to the city confident that his son's investment produced measurable improvements.

The closing sequence focuses on Par am and Sundari's personal resolution. The pilot project's success does not resolve every tension between them. Param remains inclined to quantify outcomes, while Sundari clings to the house's intangibles. Yet they have created a working partnership, and both acknowledge an affection born out of shared effort. In a final scene, Param stands with Sundari and Bhargavan in the Tharavad's courtyard as the sun lowers. He hands Sundari a printed summary of the pilot's results: occupancy numbers, guest reviews, and a proposal for future bookings. Sundari accepts the paper, reads it, and then folds it into her pocket. She looks at Param and says she will continue running the house, integrating certain new practices while holding fast to the rituals. Param agrees to respect the house's noncommercial elements and to assist when asked.

The film ends with a clear picture of their lives intertwined rather than merged into a single conformity. Param returns to the city periodically to manage broader outreach but makes regular trips back to the Tharavad. Sundari continues to run the homestay and takes on some measured changes that do not violate the house's core practices. Bhargavan continues his Kalari training and remains the keeper of physical discipline and family memory. Param's father, satisfied with the metrics and the protection of the property, maintains an arm's-length support.

No character deaths occur in the story. The final shot leaves the Tharavad as an active household: Sundari lights the brass lamp, Bhargavan resumes his practice in the courtyard, and Param sits on the verandah writing notes for the next campaign. The camera pulls back from the ancestral house, showing a compound that preserves tradition while engaging selectively with modernity, and ends with the three figures moving through their respective roles as the evening settles.

At the end of Param Sundari (2025), Sundari abandons her arranged engagement with Venu to rescue Param, who is fleeing from a chaotic chase. She saves him by diving into the backwaters, and they seal their love with a kiss, choosing each other over tradition. The film closes on a poetic and romantic note, symbolizing their happily-ever-after.

Expanding on the ending scene by scene:

The story culminates during the vibrant Onam festival, which has brought Param and Sundari closer. However, Sundari reunites with her childhood sweetheart, Venu, and their engagement is quickly arranged by her uncle, Bhargavan Nair. This leaves Param heartbroken but determined to prove himself.

Param participates in the traditional Kerala boat race, initially sidelined but eventually inspiring the rowers by singing "Yeh Dil Deewana," motivating them to victory. This act echoes Sundari's earlier advice about rhythm and balance, showing Param's growth and connection to her culture.

Despite this, Sundari distances herself after Param's father reveals that Param's visit was part of a dating app experiment, making her feel betrayed.

As Sundari's wedding to Venu approaches, Param makes a final bold attempt to reach her by climbing a coconut tree to talk to her. Their conversation is overheard, triggering a chaotic chase by Venu's family and others.

To escape, Param dives into the backwaters. At this critical moment, Sundari chooses love over societal expectations. She abandons Venu and rushes to rescue Param in the water. They share a kiss in the middle of the backwaters, symbolizing their union and defiance of tradition.

Venu is left heartbroken, and his family is shocked by Sundari's decision. The film ends with the soulful track "Bheegi Saree," underscoring the romantic and poetic closure to their story.

In terms of character fates:

• Param ends united with Sundari, having proven his worth and sincerity.
• Sundari chooses Param over her arranged engagement with Venu, embracing her feelings and autonomy.
• Venu is left heartbroken and rejected, his engagement broken by Sundari's choice.

This ending highlights the triumph of personal love and choice over tradition and societal pressure, closing the film on a hopeful and romantic note.

The movie Param Sundari (2025) does not have a post-credit scene. The film concludes with a definitive romantic climax where Sundari abandons her arranged marriage to Venu, rescues Param during a chaotic chase, and they share a kiss in the middle of the river, symbolizing their union and happily-ever-after. This final scene is the emotional and narrative closure of the film, with no additional scenes shown after the credits.

The ending is poetic and conclusive, emphasizing the triumph of love over tradition and misunderstandings, and there is no indication from available sources of any post-credit or after-credits scene extending the story or teasing a sequel.

Param, a wealthy Punjabi businessman from Delhi, and Sundari, a homestay owner in a Kerala village, develop an unexpected romantic relationship. Their North Indian and South Indian cultural backgrounds create humorous and chaotic situations, highlighting the clash and eventual blending of their diverse worlds as they get to know each other and spend time together in Kerala's picturesque backwaters.

Param is motivated to travel to Kerala after registering on a dating app that uses artificial intelligence to find soulmates. The app matches him with Sundari, and to prove the concept to his skeptical father, who agrees to invest in the startup only if Param finds his own soulmate, Param journeys to Kerala to meet her in person.

Venu is Sundari's childhood friend who arrives in the village during the festive season. He is soon to be married to Sundari, which shocks Param and creates a dilemma for Sundari about whether to choose Param or fulfill her parents' wishes by marrying Venu.

Param tries to impress Sundari by learning a Malayalam song and attempting Kalari Payattu, a traditional martial art, to connect with her culturally and emotionally. These efforts are part of his determination to win her over despite their different backgrounds.

The festive season in the Kerala village serves as a pivotal backdrop for the story, marking the time when Param plans to propose to Sundari. It also coincides with Venu's arrival, which complicates the romantic dynamics and heightens the suspense about Sundari's ultimate choice between Param and Venu.
