Unni and Sethu are two bachelor friends sharing a modest home in Madras, where music threads through their days and occasional quarrels test their patience with each other. Their life is comfortably supported by Varma, a seasoned music director who also serves as their house owner, offering a steady hand when finances get tight and keeping a watchful eye over their playful chaos. The city hums with opportunity, and their small world feels almost balanced, if a little tangled, by the music they love and the affection that quietly binds them.
One day, Unni receives a letter from his father asking him to welcome Radha, the daughter of a friend, who is arriving in Madras to join a company for a job. At the bustling railway station, the two friends are drawn to Radha's presence and begin vying for her attention, each trying to win her over with charm and wit, turning the encounter into a test of pride and affection rather than a simple introduction.
Radha finds refuge at the home of Mary, a colleague who becomes more like a sister than a landlord, offering warmth and support as Radha navigates a new city and a new life. However, Radha’s joining is delayed, and to everyone's surprise she ends up being denied the job. In the midst of this setback, Sethu introduces her to V.N Das, his manager, a confident man with a womanizing streak who uses his influence to secure a job for Radha at his company. This development sows seeds of tension between the two friends, as the path to Radha’s professional future becomes entangled with romantic rivalry and complicates their once-simple bond.
The rivalry between Unni and Sethu grows fiercer as they struggle to confess their true feelings for Radha, resulting in a series of bitter clashes that threaten their friendship and even erupt into physical confrontations. Yet love, pride, and prideful delays gradually yield to a hard-won understanding as Radha steps into a wider circle of people and possibilities. Then, Radha introduces them to Balachandran, whom she calls her fiancé, and invites them to attend her wedding without fail. This moment acts as a mirror, making them confront their foolishness and the depth of their bond.
Realizing how far they have let their vanity drift from their genuine friendship, Sethu and Unni manage to patch things up and return home with a renewed sense of camaraderie and hope. Yet the day does not end there, because back home, Sethu receives a letter from his father announcing the arrival of the daughter of another friend in Madras. The prospect of meeting a new companion reignites the journey, and the two hurry to the railway station to welcome her, eager to see what new chapter their shared life in the city will bring.
