Subramanyam 'Subbu' is a materialistic and ambitious IIM graduate who is determined to climb the corporate ladder. Subbu works under his boss, Pasupathi, who shares his ruthless drive for success. Together, they aim to acquire the company of Ramayya. Though their initial attempts fail, Subbu cleverly manipulates Ramayya's employees into selling their shares, marking Pasupathi's biggest corporate triumph. In recognition of his success, Subbu becomes engaged to Pasupathi's daughter, Riya.
During the engagement ceremony, Rishi reenters his life. Rishi is the antithesis of Subbu—an energetic, free-spirited individual who lives life without concern for material success. On the same day, they meet Anandi, a free-spirited but lonely girl, in a pub. Rishi reveals his long-held dream of traveling to Doodh Kasi, a sacred lake in the Himalayas, with Subbu.
Meanwhile, the corporate world of Pasupathi and Subbu is shaken when they lose crucial shares, threatening their acquisition of Ramayya's company. Pasupathi, enraged, threatens to end Subbu's engagement and fire him if he cannot secure the deal. Desperate, Subbu approaches Ramayya, who politely declines to sell his company. Feeling dejected, Subbu considers Rishi's proposal to visit Doodh Kasi. Rishi playfully promises to return the details of a key shareholder if Subbu agrees to the trip. This leads them to Anandi, whose father holds the critical shares needed for the acquisition.
Subbu and Rishi discover that Anandi is lonely and has no close relationships. They befriend her, though Subbu remains focused on getting her to sign over the shares. However, Anandi repeatedly postpones signing the documents, which frustrates Subbu, who is torn between his corporate ambitions and the growing bond with Anandi and Rishi.
One day, Subbu and Rishi come across an injured girl on the road and rush her to the hospital. The girl dies due to delayed medical attention, a tragedy that deeply affects Rishi. This incident sparks a heated argument between the two friends, where Rishi criticizes Subbu's materialistic lifestyle. In response, Subbu accuses Rishi of leading a purposeless life. The argument drives Rishi away.
The next day, Subbu receives a devastating phone call informing him that Rishi has died in a road accident. Shocked and grieving, Subbu and Anandi travel to Kolkata for Rishi's funeral. There, Anandi promises to give Subbu the shares if he accompanies her to Doodh Kasi to scatter Rishi's ashes.
The film then focuses on Subbu and Anandi’s journey to Doodh Kasi, guided by a local named Pemba. Throughout the trek, Subbu begins to transform, shedding his materialistic mindset and learning to appreciate the present moment. Along the way, they meet Robert, a multi-billionaire who regrets spending his life chasing wealth and missing out on meaningful relationships. Robert's story profoundly impacts Subbu, reinforcing the importance of living a fulfilling life.
Subbu's transformation is further deepened when he helps a pregnant woman in labour, experiencing genuine joy as he holds the newborn baby. This journey also allows Subbu and Anandi to grow closer, with love blossoming between them.
Upon returning from Doodh Kasi, a changed Subbu breaks off his engagement with Riya and returns Ramayya's company to him. He even applies for a job at Ramayya’s firm, symbolizing his shift away from ruthless ambition. In the film's closing scene, Subbu, now embracing a more meaningful life, asks Anandi for a "share" in her life, indirectly proposing marriage.
