Gopikrishna (
Murali) owns and drives an old bus which was received as compensation for his father's road accident. Gopi now faces many consequences due to the bus's pathetic condition. He had sold many valuable things to maintain the bus, and his friend Azhagu (
Vadivelu) was his only companion and the bus's cleaner. A mouse had eaten Azhagu's passport and spoiled his chances of going abroad. Some part of the film's comedy involves Azhagu running behind the mouse for revenge. A live TV show in which Gopi insults the City Traffic Commissioner (
Vinu Chakravarthy) lands him in more trouble when the latter commands Gopi to leave the city with the bus. His other friends, lawyers, and well-wishers try to help him with a bank loan to convert his bus into a
food truck. The plot took a turn when a girl named Vasanthi (
Radha) enters the bus as a nomad, but she was actually Gayathri, the daughter of an influential and politically powerful minister (
P. Vasu) in
Puducherry. Her father forced her to join politics, which made her leave home. Initially, Gayathri declines to leave the bus, despite Azhagu's and Gopi's constant efforts. The police traces her and takes her back to her father's custody. Her father was making arrangements for her marriage with someone else. Meanwhile, Gopi realised that he could not live without Gayathri. Gopi and Azhagu secretly enter her house, and finally, all ends well as he wins over Gayathri's father. == Cast ==
