Ranga Rao is a carefree jovial person and is better known as Poola Rangadu. He makes a living pulling horse carts and is in love with Venkatalakshmi. When both he and his sister were children, their father Veerayya used to work as a manager at a mill, owned by Purushotham. Purushotham was murdered by his business partners Dharma Rao and Chalapathi. Veerayya is framed by them and is sentenced to life imprisonment leaving his children completely helpless. Despite hardships, Ranga has managed to raise his sister Padma with great care and loves her very much. Venkatalakshmi's no-good brother, Narasimhulu, has an eye for Padma, but she falls in love with Dr. Prasad. Ranga gets her married to the doctor. However, he happens to be the son of Purushotham. A vengeful Narasimhulu uses the fact that Padma is Purushotham's alleged murderer Veerayya's daughter to poison her mother-in-law against her who promptly throws the now pregnant Padma out of the house. Ranga becomes furious at this and beats up Narasimhulu. This ends up getting Ranga arrested and he is sent to prison for a year. In jail, Ranga bumps into his father who tells him about how he was framed. Once his one-year sentence is up, Ranga decides to prove his father's innocence at all cost. With this intention, he makes his way into Dharma Rao's house where he cleverly stirs up trouble between Dharma Rao and Chalapathi. Through various schemes, Ranga finally manages to prove his father's innocence. Padma is reunited with her husband and Ranga marries Venkatalakshmi.
