Vijayalakshmi Balakrishnan, nicknamed Vijji, is a middle-class housewife living in Chromepet with her family. She embraces life with a contagious energy, sharing laughs and small wins with her loving husband Baalu and their 11-year-old son Siddhu. Vijji dreams of stepping into the working world, but her lack of a completed high school education leaves her with few obvious paths toward a white-collar career. Her elder twin sisters are quick to point out her educational gaps, often poking at her ideas and doubting that she can ever truly climb out of the cycles of domestic routine. Yet Vijji herself is undeterred, thriving on every contest she can enter—whether it’s a singing showdown, an athletic challenge, or even a playful lemon-and-spoon race—and somehow turning each small victory into a reason to keep reaching for more.
Her home life is affectionate but under strain. Balakrishnan, a manager at a tailoring firm, works in a place that feels more like a museum of ages—most of the staff are well over sixty, and the new young owners are distant and sometimes unreasonable. The grandson of the firm’s founder has stepped into leadership with a snide, dismissive attitude, creating a tense workplace for [Baalu], who bears the brunt of the frustration with patience and devotion to his family. Siddhu, their energetic son, often finds himself teased at school by peers who flaunt expensive gadgets, underscoring Vijji’s quiet fear that her own untraditional path might someday ripple into her son’s life as well.
One bright moment arrives when Vijji wins a contest run by her beloved radio station. The call that follows comes from Anjali, the station’s top RJ, who catches Vijji off guard by asking her to perform a tune she chooses on the spot. A mischief-loving, retro-tinged song becomes the spark that sets Vijji on a new course. The next day she heads to the station to claim her prize and encounters a poster announcing auditions for an on-air role. A twist of fate lands Vijji in a formal audition, where her quick wit and unbridled charm—along with a moment of unintended sensual delivery when Kumki recites a line—capture the attention of the station’s boss, a decisive manager named Maria. In that moment, Vijji learns that the opportunity she’s dreamed of might finally be within reach.
Maria sees in Vijji not just energy, but a rare ability to connect with people. She proposes a bold format: a call-in night show where listeners share their troubles and Vijji offers guidance. It’s a project that will require a blend of warmth, humor, and a fearless conversational style—qualities Vijji has in abundance, even if she’s stepping into unfamiliar territory. The decision to take the job isn’t simply about a paycheck; it’s a leap toward self-actualization, a way to balance out the domestic duties with a public voice that can help others.
From the outset, Vijji’s approach is both practical and playful. She tests the waters with a lighthearted prank—calling a nearby grocery store to request a broom delivered to a non-existent Fifth floor—and even talks to her husband in a flirtatious, teasing voice to test the effect of her evolving persona. Her audacity isn’t about shocking people; it’s about proving to herself that she can navigate new spaces with confidence. When she finally commits to the job, Balakrishnan is initially wary, worried that the pressures of the new role could destabilize their already fragile balance at home. Yet the bond between them—built on trust and genuine care—helps him see that Vijji’s growth could ultimately strengthen the family.
As Vijji’s show launches, she learns to handle difficult calls with poise. A caller seeking something beyond the ordinary asks for a kind of song that she can scarcely resist performing for her own husband, a moment that stirs tension for Balakrishnan as he feels sidelined by the new, jubilant energy in Vijji’s life. The workplace dynamics at the radio station—where Maria supports Vijji’s ambitions and the ride between professional fulfillment and domestic worry becomes a recurring theme—grow richer and more complex. The audience responds warmly, and Vijji discovers a rhythm and a sense of purpose that she had long sought. The show’s success brings a stream of happiness into Vijji’s days, yet it also magnifies the balancing act she must perform between work obligations and family responsibilities. The family’s happiness is not a straight line; it fluctuates as Vijji’s professional life expands and her home life experiences moments of strain and strain relief in turn.
The harmony of Vijji’s life is jolted when Siddhu’s school days reveal a troubling incident. The principal discloses that Siddhu and a friend were poised to sell a batch of stolen phones, including one that belonged to Balakrishnan, to help fund a gaming console. They also forged Balakrishnan’s signatures on school diary remarks, leading to Siddhu’s suspension. The revelation devastates Vijji and her family, and her sisters urge her to quit the radio gig to focus on Siddhu’s welfare. They argue that her absence at home is fueling Siddhu’s missteps. But Balakrishnan stands as a steadfast pillar of support for Vijji, defending her right to work and the family’s need to weather this storm together.
Vijji refuses to be boxed in, choosing to stay true to her ambitions while confronting the emotional turmoil at home. The show’s success continues, and Maria remains a steadfast ally, recognizing Vijji’s unwavering dedication. Yet the incident with Siddhu triggers a cascade of emotions: Vijji’s commitment to her job collides with the concerns of her family, and she has to make a painful choice. When Siddhu disappears and leaves a note lamenting the burden his actions have placed on his mother, Vijji is shaken to her core. The note reveals Siddhu’s vulnerability and his desire for his mother’s strength, asking his father to back her up during this challenging time. The next day, the police locate Siddhu and return him home. In a decisive moment, Vijji returns to the office to resign, overwhelmed by the emotional upending around her.
Yet the story doesn’t end with resignation. On a chance encounter, Vijji notices a receptionist in a dispute with the tiffin service workers and recognizes an opportunity to bring a sense of order back to the household’s daily life. With renewed resolve, she convinces Maria to hand over the tiffin contract to a service that can better support the family’s needs. The film then advances to a future where life has found a new cadence: about a month later, Balakrishnan is shown running the tiffin business, while Vijji skillfully manages both her household and her radio commitments, operating with her characteristic blend of practicality, warmth, and fearless energy. The balance between work and home remains dynamic, but Vijji’s strength and creativity continue to shape a life that is as rich in love as it is in ambition.
In the end, the story celebrates a woman’s resilience, the power of a supportive partner, and the idea that following your passion can coexist with caring for those you love. It’s a portrait of a modern family navigating the joys and trials of growth, with Vijji guiding the way through humor, heart, and an unshakeable determination to live life on her own terms.

In the bustling suburb of Chromepet, Vijayalakshmi Balakrishnan—affectionately known as Vijji—juggles the rhythmic chaos of middle‑class family life. She shares a modest home with her diligent husband Balakrishnan, a weary manager at a tailoring firm, and their energetic eleven‑year‑old son, Siddhu. Though her formal education stopped short of high school, Vijji’s spirit is uncontainable; she thrives on contests, from singing challenges to quirky neighborhood races, and quietly dreams of stepping beyond the kitchen’s familiar walls.
