An innocuous and good-hearted lad Simhadri (Jr. NTR) is handpicked by Ram Bhupal Varma (Nassar). The bond Ram Bhupal Varma and Simhadri share is like that of a father and son. Kasturi (Ankita) is the grand daughter (daughter's daughter) of Ram Bhupal Varma. Kasturi likes Simhadri a lot. Once in a week, Simhadri visits a mentally retorted girl called Indu (Bhoomika Chawla). He entertains her and passes on the money to her caretakers (Rallapally and Ragini). After coming to know about Ankita's liking towards Simhadri, Ram Bhupal Varma decides to get them married. At this point of time, it is revealed that Simhadri is very close to a mental girl Indu. The alliance breaks off. Mean while a bunch of gangsters are in search of Simhadri. They found him at the banks of Godavari River along with Indu. In that confrontation between gangsters and Simhadri, Indu gets injured. When she comes back to her senses, she becomes a normal girl. The first thing she does then was to stab Simhadri.Simhadri is hospitalized and is dying. Then we see hoards of buses coming from Kerala to see Simhadri, whom they call as Singamalai. In the flashback it is revealed that Ram Bhupal Varma's elder daughter Seeta (Seeta) elopes with a guy (Bhanu Chandar). They settle in Kerala. Simhadri takes up the job of uniting family and visits Trivendrum. There he finds Indu as the grand daughter of Ram Bhupal Varma. He convinces the separated family and when the reunion is about to happen, Seeta is stabbed by a local goon Nair (Rahul Dev). A rowdy named Bhai Saab (Mukesh Rishi) controls the mafia of Kerala. Nair and Bhai Saab belong to the same mafia. Simhadri takes law into his hands and eradicates goons in Kerala. The local Kerala people starts calling him 'Singamalai'. When Simhadri along with Indu and her father is about to return to Vizag, Simhadri realizes that Indu's father's suitcase has a bomb. Now Simhadri has two choices:to murder Indu's father so that all the lives on the train can be saved or he can let the bomb kill everyone on the train, including Indu's dad and Indu herself. Simhadri chooses to murder. As soon as Indu sees Simhadri kill her father, she gets hit in the head with a pole, causing her to become mentally challenged. After the flashback was revealed, lots of people come outside the hospital, chanting Singamalai Singamalai. Bhai Saab's men come to the hospital to kill Simhadri, but Simhadri, who had recovered and with the help of his friends and police, he takes down Bhai Saab and his goons.
