Babu and Yesu are close friends and delivery men living together with their friend Naresh Agastya, who is unemployed and spends much of his time binge-watching crime TV shows. Life isn't easy for Babu, as he struggles to make enough money to get by. One day, Yesu confesses that he often steals from his clients and suggests Babu try the same approach to earn extra cash. Initially, Babu is hesitant about resorting to theft, but eventually decides to follow Yesu's advice.
The very next day, Babu heads to a secluded, gated apartment complex, where he encounters a series of unusual events. He meets Jhansi, who plays Damini, a resident of flat 503, when she accidentally bumps into him while riding her scooter. During his delivery, Babu is also stopped by Raja Chembolu, a police officer conducting passport verification, and encounters Ravi, a fellow resident. His main task is to deliver a package to an elderly lady in apartment 401. While there, Babu slyly steals a ₹500 note, trying to convince her that she has underpaid him. When she catches on to his trick, a struggle ensues, resulting in her falling to the ground.
Babu, overwhelmed and panicked, imagines Yesu and Srinivasa Reddy (playing Abhi) advising him on how to cover up his involvement. He then moves her body to her bedroom, making it appear as if she died peacefully in her sleep. During this moment, he notices Gundu Sudarshan, the security guard, who has been lurking in the background. The guard later enters the apartment, claiming to fix the shower, but instead discreetly replaces a memory card in a spy camera that had been installed earlier.
Hiding in the bathroom, Babu watches as the security guard removes the camera card. Desperate, he messages Yesu and Abhi for help. Meanwhile, Bujji, who has been at home with headphones on, invites Ravi into the apartment to smoke marijuana. It is then revealed that Bujji herself has drugged the old lady by contaminating her water bottle, unintentionally administering the same substance to Babu, causing him to fall asleep in Bujji's bedroom.
When Babu wakes up, he finds himself in the living room next to the dead body of the old lady. Horrified by what has transpired, he quickly escapes and meets Yesu downstairs before heading back home. In his bag, Babu notices that his delivery packages are missing and instead finds a staggering amount of ₹50 lakh (approximately US$59,000). He also discovers Banerjee’s mobile phone, which helps him realize that the elderly lady had been murdered—Banerjee was the victim.
With the help of Yesu and Abhi, Babu devises a plan to escape. They aim to retrieve his bike and the remaining packages while deleting all footage from the security cameras to cover their tracks. When they reach apartment 401 again, they are relieved to find the old lady alive; however, Babu soon learns that the girl he had met earlier was actually not Tejaswi, but another individual from flat 503, named Myra, who is a drug dealer. During this encounter, Babu also realizes that he initially woke up in apartment 501, not 401.
Inside apartment 501, they discover Banerjee's body and find the packages Babu had ordered. They also come across an unconscious girl in a hidden drug lab—revealing that the flat belongs to Ravi. Further investigation uncovers Ravi's dead body, confirming his involvement in the drug trade and the violence surrounding it. Babu, with some tension, manages to retrieve the spy camera from apartment 401 after threatening the security guard. The girl, Myra, wakes up and fiercely resists, leading to an interrogation where she identifies herself as Myra, a drug dealer caught in the crossfire, who had come to Ravi's to stockpile drugs.
The plot thickens as Babu uncovers that Banerjee came to Ravi's apartment seeking information about the neighbors, only to stumble upon the drug lab. Under the influence of the drugs, Myra kills Banerjee during a negotiation for a bribe, and Ravi later kills Myra and Abhi when their plans threaten to expose them further. Abhi, revealed to be the mastermind behind the drug operation, brazenly orchestrates an escape plan, knocking out Myra and murdering Ravi in the process.
Their attempts to escape are complicated by Babu's discovery of Banerjee's body. Abhi then stages a criminal scene to frame Babu, planning to leave him trapped amid the chaos. But Babu, furious and determined, destroys the drug lab, causing a massive explosion that releases all the drugs into the air, unintentionally making everyone in the vicinity high and adding chaos to their escape.
Weeks later, Babu and Yesu are interrogated by a detective, who reveals that both Abhi and Myra have become mentally unstable due to their experiences. The detective, seeing an opportunity, lets them go free, accepting a hefty bribe in exchange. Interestingly, the pre-credits scene shows the Prime Minister of India announcing the demonetization of all ₹500 and ₹1000 notes, rendering the stolen money completely worthless, which leaves Babu and Yesu pondering the bizarre turn their lives have taken.
This story offers a gritty, darkly comedic look into desperation, crime, and the unpredictable consequences of trying to cheat the system, highlighting how a simple act of theft can spiral into a complex web of violence, deception, and chaos.
