The story begins when a young lawyer reopens a closed case, claiming that the man convicted of rape and murder was innocent. When the court asks for proof, she reveals that she is his daughter.
An intellectually disabled man, Ramesh Arvind, comes from a family of army employees and hopes to follow the same profession, but his disability prevents him from doing so. Instead, he owns and drives a rickshaw to support himself and his daughter (Baby Yuvina). The two share a happy life and save money to buy her a toy aeroplane.
When they visit a shop to purchase it, they find themselves slightly short of money and decide to return the following day. However, the daughter of a police chief wants the same toy and buys it immediately, prompting Ramesh to argue with the police. The next day, he encounters the girl while driving his rickshaw. She offers to take him to another shop where he can find a similar aeroplane, but she is subsequently found dead. A woman claims to have witnessed Ramesh raping her and reports him to the police.
