Plot

The life of an auto driver becomes a mess due to unexpected issues in the family.

The film begins with Radhakrishnan hiding from the police, who are visiting the area. He then runs through the village and into the fields. Then we see a flashback of Krishna's life and the events leading to him running.

Past: Krishna is a humble auto driver who is sincere and honest. He is content with his life, which revolves around the auto, his wife Savithri, and his two kids. Krishna has a good friend, Vappa Bhai. His kids study in a government school, and he wishes to improve their standard of education by admitting them to a private school. He teaches his kids good morals.

He also reveals to his daughter how he fell in love with Savithri. One day, a man left some gold jewellery in his automobile, and Krishna helped return it. The old man's name was Maarisaamy. Krishna and Bhai visit his house and give him the jewellery. Maarisaamy reveals that he brought the jewellery for his daughter's engagement ceremony. After that, one day, Krishna meets Savithri at a bus stand. He finds out they cancelled the alliance because of dowry concerns.

Krishna, Mayilu (a house broker), and Bhai help Savithri and her father find a new home. At the same time, Krishna falls in love with Savithri. Krishna helps him find four suitable grooms. He smartly puts his horoscope with them and gives it to Maarisaamy. Krishna then tells Bhai that they accepted him as a suitable groom. So Bhai shows Maarisaamy Krishna's newly built house and tells him that Krishna wanted to marry an educated girl. Bhai persuades Maarisaamy that Krishna will care for Savithri dearly. Eventually, Maarisaamy decides to accept the engagement. Finally, after many hurdles, Krishna and Savithri get married at the temple, which concludes the love flashback.

One day, when taking his kids to school, he sees builders working on a plot of land. A man tells Krishna that a Malayali man brought a piece of land and informs him that he knows the town, and if you help him sell, he can get the commission he needs to improve his children's education standards. To do so, he promises real estate businessman Madhavan that he will assist him in selling all the plots to his villagers. Eventually, he becomes a house broker, but his wife convinces him it's not a good choice. Soon, Krishna sells all the properties, and Madhavan collects all the money. Krishnan gets drunk with Madhavan, and his wife gets angry. The following day, Krishna gets cheated since Madhavan runs away with the money. Krishna becomes confused since he feels guilty that his villagers trusted his word. Madhavan's good-hearted assistant tells him that Madhavan's house is in Kerala. It returns to the film's beginning.

Present: Krishna travels to Kerala to meet Madhavan's mother, but he is not there. He works as a toilet cleaner and befriends two workers who help him. At home, Savithri realises that the house documents are gone, and the villagers become hostile to them and insult Krishna. Bhai provides support for them and gives them money and food. Krishna helps Philomy's daughter, Christy (whom he sees as his daughter). He earns the trust of Philomy. Eventually, Krishna's kids grow up, and Savithri decides to use his son's salary to pay Bhai. He reveals that his dad came to him the night he eloped and gave the house documents to Bhai. Bhai informs them that Krishna is the one who sent money for their studies. Savithri, Krishna's son, and Bhai visit Kerala. According to Krishna's friends, he left the town shortly after Madhavan's mother died, and they discovered his objective.

Eventually, in Varanasi, Krishna stays with two priests. They are suspicious of him, and he tells them his children should win in the village where he lost and is seeking forgiveness. The priest says that Krishna is a Maamanithan. One day, he sees Madhavan, who is now a beggar. Madhavan begs for Krishna's forgiveness, but Krishna tells him that he left his mother orphaned, and she died. Madhavan commits suicide by drowning, and it breaks Krishna's heart. Eventually, the priest helps Savithri and his son reunite with him, and they go to see his daughter.
