J. Balasubramaniam "JB" is a wealthy and popular industrialist who has been working without a vacation for two years straight. Exhausted after a Europe and New York trip, he decides to take a vacation at his bungalow in Shimla. Upon his arrival, he discovers that his caretaker Krishnaiah has rented the bungalow to a Bangalore-based couple, Punyakodi and Pappamma, and their daughter, Geetha.
Krishnaiah and his wife leave for Kasi after taking the money for the rent, leaving Krishnaiah's daughter Kannamma, and his brother-in-law Ramaiah, in charge of the house and the guests. JB decides not to reveal his true identity, instead pretending to be JB's personal secretary Balu, and pays the rent for a place in his own house. Ramaiah, who has never met JB, takes the money and gives JB's room to Balu without realising they are the same man.
Balu plays continual pranks on Geetha, during the course of which he also falls in love with her. She too falls in love with him, but circumstances and their egos, prevent them both from expressing their feelings. One day, Balu pretends to suffer from chest pain, which scares Geetha, causing her to finally admit that she loves him.
The next morning, when Geetha and Ramaiah go to Balu to enquire about his health, Balu, exiting from the bathroom, fails to see that Geetha is there. He tells Ramaiah about the prank he played on her. Enraged at having been deceived by Balu, Geetha begins to question whether or not his professed love for her is real. She brings her friends, who are vacationing in Shimla, to the residence and tries to drive Balu out of the house. When her plan backfires and her friends start supporting Balu, she becomes spiteful and tells her parents to move forward with a planned marriage to Sekar, her maternal cousin.
Geetha reconciles with Balu after he saves her from a weightlifter named Sitting Bull. But by the time Balu confesses his love for her, Geetha's engagement is already fixed to Sekar. Sekar turns out to be a school friend of JB, but he agrees to play along with the trick. When he discovers that Balu and Geetha are truly in love, he steps aside, wishing the couple well. When Balu finally reveals himself as JB, Geetha, again not knowing what to believe, thinks the wedding plans are yet another of his pranks and tries to run away. He finds her and clears up all of the misunderstandings between them. The two then get married.
