Laxmi is a widowed, loving mother to Lalita, a bright college-going daughter, and to her son Ravi, a fellow student who impresses everyone with his intellect. At the same college, Ravi is a talented, earnest student, and Vijay Choudhury arrives as an engaging English professor who quickly forms a rapport with the students. After a few initial misunderstandings, Lalita and Ravi find themselves drawn to each other and fall in love. During a college function, Lalita takes the stage to sing “Patjhad Saawan Basant Bahaar,” but forgets the lyrics; the music unexpectedly falls into place when Vijay Choudhury finishes the tune. Curious about how he knew the song, Lalita learns that it is a famous piece and was her mother’s favorite. She reveals that she learned the tune from her mother, and the moment deepens the bond between them.
The narrative then shifts to a flashback that centers on Vijay’s home life. In this past, Vijay Choudhury and Laxmi are a happily married couple. Vijay is a professor, while Laxmi is a gifted singer who partners with Mr. Kumar on stage, forming a popular musical duo. This success also sows seeds of misunderstanding in Vijay, who begins to feel a rift between them. He eventually urges Laxmi to leave their home. The turning point comes when Vijay learns that Mr. Kumar is about to marry, which slowly clears the earlier misconception, though the underlying tension leaves Laxmi unaccounted for at that moment.
Back in the present, Laxmi already knows about Lalita and Ravi’s love and seeks to protect the family. She consults Advocate Dharamdas, Ravi’s maternal uncle and guardian, who arranges Lalita’s marriage to Ravi on the condition that they pass their final exams with good marks. Lalita asks Vijay Choudhury for home tuition, and during a visit to Lalita’s home, Vijay discovers Laxmi dressed as a widow, shocking him once again with lingering misconceptions. He resigns from the college, a decision Lalita relays to Laxmi, who then sits down with him to explain her new identity and the circumstances that led to it.
A second flashback reveals Laxmi’s journey after leaving home. She travels to Pune to visit a friend, Sunita (the only photograph shown in the film), and along the way she saves a little girl named Lalita from an accident. The girl’s father, Prem Kapoor, thanks Laxmi and invites her to stay for Lalita’s upcoming birthday, urging her to act as Lalita’s mother for the day since Lalita is a heart patient who doesn’t know about her mother’s death. Though initially hesitant, Laxmi agrees and conceals her true status by adopting a widow’s appearance. On Lalita’s birthday night, sher a kidnapping occurs: Shera abducts Lalita to demand Prem’s property as ransom. Prem agrees, but he is stabbed by Shera while shielding Lalita, and Shera is imprisoned. Before dying, Prem pleads with Laxmi to care for Lalita as her own daughter. To shield Lalita from this painful shock, Laxmi continues the deception and remains in widow’s attire.
Returning to the present, Vijay apologizes to Laxmi for the double misunderstanding and withdraws his resignation, resuming their arrangement to tutor Lalita and Ravi at Lalita’s home. Shera emerges from prison with a renewed determination and learns the fate of Prem’s family. The discovered truth strains the relationship further when Ravi informs Lalita about the affair between her mother and Vijay Choudhury. Lalita rejects the idea, leading to a breakup between her and Ravi. Ravi confronts Vijay and warns him to leave the city, while Shera uses the rift to his advantage and accuses Vijay of responsibility for Ravi’s actions. Laxmi, sensing the danger, seeks out Vijay to mend things, and Lalita is stunned when she sees her mother hug the professor. Overwhelmed, she attempts suicide but is saved by Ravi. Lalita resolves to leave with her father’s photograph, and Laxmi tries to stop her, but Lalita departs nonetheless.
To heal the rift, Vijay seeks counsel from Advocate Dharamdas, who sets the record straight for Ravi and helps ease tensions within the family. Ravi, furious at Vijay’s presence, is calmed by Dharamdas’s recounting of the past. The story escalates when Shera kidnaps Lalita again, demanding the same ransom as fourteen years earlier. Laxmi agrees to the terms and goes to confront Shera with the money. The climax features a fierce confrontation where the conflict resolves amid a tense showdown. In the end, Gulshan Grover(/actor/gulshan-grover), playing Shera’s nephew, falls during the struggle, a reminder of the criminal web surrounding the family. Police arrive as the dust settles; Ravi stops Lalita from acting rashly, and Dharamdas recounts the family’s true history to bring about reconciliation. Lalita, faced with the truth and tempered by her love for her mother, forgives Laxmi, and the family finds a path back to each other, restored by understanding and a renewed sense of belonging.
