Ramu (N. T. Rama Rao) a young & energetic guy, is the only son of I. G. Raja Shekaram (Jaggayya). His father wants him to see him as a police officer but his timid mother Meenakshi (S. Varalakshmi) does not agree with it because she is very much scared about this job. Meanwhile, Ramu falls in love with a beautiful girl Vani (Sridevi). Ramu plays a drama, as he is working in Vani's company and on the name of promotion he leaves to the police training. Parallelly, at a town called Nagarajapuram happens a lot of atrocities. Done by three traitors Narasimham (Satyanarayana), Bhairavaiah (Allu Ramalingaiah) & Menaka (Kavitha) who behave like respectable citizens to the society. These people perpetrate many activities such as smuggling, gambling, prostitution, women trafficking etc. No one has guts to question them and any police officer comes to investigate this case will not be returned alive. I. G. Raja Shekaram takes up this case very seriously. He transfers his nephew Inspector Suryam (Mohan Babu) to that area but they keep him also in their custody by kidnapping his sister Radha (Rajyalakshmi). Finally, Raja Shekaram himself camps but these traitors attack on him and in the shootout, Raja Shekaram loses his limb. At the same time, Ramu successfully completes his police training and comes back. But seeing his father's condition as a volcano bursts in his heart. Now Ramu wants to take revenge against those criminals. He requests Govt to give his posting at Nagarajapuram and they accept it. Ramu takes his father's blessings and asks him not to reveal this secret to his mother because she may get frightened.
Ramu reaches Najarajapuram and directly gives warning to the three traitors. After that Ramu catches them red-handedly and presents them in the court but they escape from the sentence by showing the false proofs. On that night these people capture Ramu, torture him very badly and throw him on the road. They keep their danger flag as a symbol, that’s why no one comes forward for his rescue. Vani passing from that way takes him to hospital. After recovery, Ramu crushes them all and they put a case on him. In the court, he shows the evil deed happened to him as a proof by which the court decides him as an innocent. Now Ramu understands that anger is not only the source to catch hold of these people it should even require a proper wit. He changes his attire along with Vani and in various forms of disguise he collects all the pieces of evidence against them and also protects Suryam’s sister Radha. Narasimham comes to know regarding this, so, he kidnaps Rajashekatram and also kills Meenakshi. Knowing this Ramu falls like a thunder on them smashes their entire kingdom and makes them arrest. Finally, the movie ends on a happy note with the marriage of Ramu & Vani.
