Plot
Mario is a game designer from Hyderabad who, along with his friends Bhadram and Maggie, develops a successful video game. However, they soon discover a bug that causes the game to crash at higher levels. Mario contacts Kalyan, the programmer, for help, but Kalyan informs them that he is getting married and invites them to Rayalseema, promising to fix the code after the wedding.
Kalyan’s father-in-law, Bhooma Reddy, is a chieftain who rules the village of Rudravaram and conceals his violent nature and stockpile of weapons until Kalyan marries his daughter, Pushkala. Nandini Reddy, the daughter of Bhooma's close aide Bukka Reddy, also arrives for the wedding. As Mario and his friends drive to Rudravaram, they accidentally hit a man who bites Bhadram before being taken away by an old man. Further along the journey, they encounter Veera Reddy, Bhooma's arch-rival, who attempts to kill them, but they manage to escape. Mario learns that Veera Reddy plans to kill Kalyan after the wedding, but Kalyan dismisses his warnings.
Bhadram's condition worsens as he transforms into a zombie, spreading the virus to others. Bhooma Reddy investigates the virus, while Mario's attempts to stop the wedding are thwarted by Nandini. On the wedding night, Veera Reddy's men kidnap Kalyan. Mario and Nandini argue until they witness a zombie attack and lock themselves inside a house with Maggie and Kasi Reddy, eventually escaping by tricking the zombies.
The group attempts to rescue Kalyan from Veera Reddy's house, where it is revealed that Nandini is actually Sailaja Reddy, Veera Reddy's daughter, who had been sent as a spy. They escape with Kalyan, but Veera Reddy and Sailaja pursue them. Veera Reddy is attacked by zombies, and a grief-stricken Sailaja joins forces with Mario. During their escape, Kasi becomes trapped, and Maggie is bitten, forcing a heartbroken Mario to flee.
Mario remembers the old man from earlier and confronts him, discovering a hidden laboratory and the original zombie. The old man, a disgraced virologist, reveals that he created the zombie virus while developing a COVID-19 vaccine. He attempts to show Mario the location of the cure, but the zombie kills him before Bhooma Reddy rescues the others. Mario then learns that the cure is hidden near a temple symbol.
On their way to the temple, Sailaja realises that she was scratched by the original zombie, but Mario insists on bringing her along. They find Veera Reddy alive at the temple. Although initially furious with one another, Bhooma Reddy and Veera Reddy join forces to hold off the zombies. As Sailaja begins to turn, Mario discovers that the cure lies in water flowing from a Shiva Lingam. He lures the zombies into the water, curing them.
Mario is hailed as a hero for stopping the virus, and both families, along with the cured Maggie and Bhadram, reunite joyfully.
