Ram Prasad (Kick Shaam) and Lakshman, aka Lucky, (Allu Arjun) are brothers and pole opposites. While the former is an honorable and driven Assistant Commissioner of Police, the latter is a happy-go-lucky guy who is constantly at odds with his brother. Criminal turned politician Maddali Shiva Reddy (Ravi Kishan) and his goons hold a squad of police officers at gunpoint, and force Officer Rajeev (Rajiv Kanakala) to kill his commanding officer, ACP Sameer, to save the lives of the rest of the officers. Ram is motivated to prevent Shiva Reddy’s participation in the upcoming elections.
Lucky falls for Spandana (Shruti Haasan), daughter of the wealthy Bheem Prakash (Prakash Raj). After meeting Lucky on a regular basis, she reciprocates his love. Ram comes to know of Lucky’s relationship and tells Prakash that Lucky is lazy and good for nothing as retribution for a previous prank, and Prakash tells Lucky he cannot marry his daughter. Lucky confronts Ram, and they start fighting. When Lucky doesn’t stop, he’s slapped by his mother for the first time in his life. Emotionally shaken and angry at his brother, he steals Ram’s Jeep, in which Ram was transporting files that incriminated Shiva Reddy in numerous crimes. Lucky is then attacked by Shiva Reddy’s men, and the Jeep goes up in flames along with the files. Lucky beats up the goons, who then reveal they meant to kill Ram and dispose of the files on orders from Shiva Reddy. Lucky becomes infuriated and abducts Shiva Reddy from his nomination parade. He lets Shiva Reddy live since Ram was not killed, but severely wounds him and leaves him hanging from a tree.
After recovering and being elected a Member of Legislative Council, Shiva Reddy starts to take revenge on Lucky and his family. After hiring people to publicly shame Ram with false stories and get him suspended from the police force, Shiva Reddy pulls strings and has the government demolish the family’s house, claiming that it was illegally built. Ram is then informed that it was Lucky that stole his Jeep. Lucky admits to his mistake but says that Ram would’ve been killed if Lucky hadn’t stolen the Jeep. Ram retorts that Lucky wasn’t trying to save his life, and kicks Lucky out of the family after berating him for what his mistake has cost them.
Lucky is abducted by Shiva Reddy, who brutally beats him and leaves him hanging from the same tree Lucky hung him from. Lucky escapes and plans to take revenge on Shiva Reddy with the help of Home Minister Govardhan (Posani Krishna Murali), who owes Lucky for his promotion from MLA. Lucky fools Govardhan by staging a hospital room where he seems to be dying and a fake doctor claims he has one day to live. Govardhan says he will grant any wish Lucky asks, and Lucky requests to be instated as a special police officer and that Govardhan do a solitary 12-hour prayer so that there might be a chance of his survival. His requests are reluctantly accepted, and, for one day, he is put in charge of a team of frustrated police officers headed by Kill Bill Pandey (Brahmanandam).
Lucky first arrests Ram, knowing that his brother would prevent him from bringing justice to Shiva Reddy illegally. When meeting with Shiva Reddy’s auditor, Lucky learns of a few of Shiva Reddy’s factories and raids them. When Shiva Reddy calls Lucky’s special forces team to berate them, they claim ignorance and Lucky sends Pandey to Shiva Reddy in person to get a list of his factories under the pretense that they’ll know which factories to not raid. Using the list and the media, the special forces team invades and exposes Shiva Reddy’s illegal operations. Govardhan’s prayer finishes and after the Chief Minister (Sayaji Shinde) tells him of his mistake and scolds him, he releases and reinstates Ram. Lucky fights and defeats Shiva Reddy, but after he cuffs him, Ram appears and cuffs Lucky. Govardhan and the Chief Minister want to publicly hang Lucky for illegally arresting a government official and humiliating them, but Ram tells them that people wouldn’t take well to killing the man who exposed Shiva Reddy as a criminal. He turns on the TV and shows them that the media believes that Govardhan and the CM orchestrated the successful one-day operation to take down Shiva Reddy and that the public plan on re-electing them because of their heroics. Govardhan and the CM are satisfied with the golden opportunity they’ve received, but Lucky, threatening to reveal the truth to the media, blackmails them into also installing his special forces team full-time with Pandey as its leader and giving independent powers to sincere police officers like Ram. Realizing Shiva Reddy has been listening to them, they let him run free out into the street, where he is shot and killed by Rajeev. Lucky steps down as a special officer with his involvement not known to the media, and Pandey speaks to the media as Lucky reunites with his family.
