Gana is a youth who beats crooked people that escape punishment due to faults in the legal system. He is raised by his paternal uncle Sripati, and berated by his father Umapati for leaving the military and not having an aim in life. One day Gana is sent to a neighbouring village to meet his prospective bride, Mahalakshmi. She is the daughter of his father’s friend, Jaya Prakash, who is a sincere Indian Administrative Service (IAS) officer and politician. However, Gana meets Hansitha Reddy, who is revealed to be the local Member of the Legislative Assembly (MLA), and falls in love with her. He tells his father that Mahalakshmi rejected him because he gets into fights.
Dhanush is the son of a chief minister; he kills a farmer for refusing to give up his lands. Later, a prominent businessman comes to Dhanush to escape punishment for raping and murdering a college girl. The victim’s parents seek the help of Hansitha to get justice. At the trial, a new defence lawyer twists the case, making it seem like the girl provoked her beating by blackmailing the accused, and the judge decides in favour of the lawyer’s argument. Gana learns about the lawyer and beat him up, cuts off the legs of the rapist. Dhanush takes this as a challenge to his influence and becomes incensed.
Hansitha falls for Gana and promises to marry him if he swears in the presence of God that he will stand behind her and never get into fights. He is about to do so at the temple when a badly injured Mahalakshmi arrives, running from people who try to kill her. Gana holds her up, beats everyone who tried to kill her, and ultimately gives Mahalakshmi courage.
Narrating a flashback, Mahalakshmi explains how Dhanush tried to blackmail her father. Her father had been protecting farmers so they wouldn’t have to sell their lands. This infuriated Dhanush who killed the farmers. When Mahalakshmi intervened, slapping and insulting Dhanush (she had also called him a zero, which angered him more), he killed her father and tried to kill her. She narrowly escaped and had run for four days to find Gana, whom she had fallen in love with.
