Bhaskar, the eventual leader of the rival faction group, operates from Charlapally jail, and his main aim is to kill Swamy.

Shankar is an orphan raised by Swamy, and grows up to become the latter's body guard and right-hand man. Without asking for her consent, Swamy settles his sister Nandini's marriage with the son of Naayar. Nandini doesn't like this proposal and plans to get out of it. She lies to Shankar, saying that she wants to marry the man she loves, Kumar. She seeks Shankar's help to escape from home. Shankar, in a fix, reluctantly agrees. Before escaping, Nandini writes a letter to Swamy, saying that she is actually in love with Shankar, and that they are eloping. This letter creates a rift between Shankar and Swamy, who feels betrayed. Later, Nandini reveals to Shankar that she is actually in love with him, and not Kumar. Shankar is shocked. Meanwhile, Bhaskar tries to take advantage of the rift between Swamy and Shankar and plans his attack. During their time together, Shankar too gradually falls in love with Nandini. Eventually, Swami and Shankar come together and fight Bhaskar. They finally reconcile, but Swami succumbs to his injuries. Shankar and Nandini marry and eventually have a son, whom they name Swami.
