Karthik, an IAS aspirant, and Subbalakshmi, a pretty woman, fall in love. But Karthik’s father opposes the match.

Karuppusamy (Karan) is a happy-go-lucky guy who is a small-time contractor for cycle stands. When not at work, he kills time with his friends, taking part in their mimicry troupe where he is famous for his Rajini look-alike acts. Life goes on for the protagonist until Raasathi (Meenakshi) stumbles upon his life. An aspiring medical student, she relates Karuppusamy’s benevolence to her late mother’s. Soon after, they both become victims of the stupid cupid’s bait.
Although in love with the uncle, Karuppusamy insists that education should be her priority over romance. Besides, their love affair wreaks havoc in Raasathi’s upper caste family, which is known for cast prejudices.
