Raghava is an unemployed lovable person, who spends his days playing cricket with his friends. He suffers from an irrational fear of ghosts and retreats to his home after sunset. His fear is so great that he prefers to sleep beside his mother and has her accompany him to the restroom at night. This creates a major annoyance in the household, including Raghava's brother, sister-in-law and their children.

One day, Raghava and his friends are forced to abandon their usual cricket ground and find a new one; they unwittingly select an abandoned ground which is rumoured to be haunted. A bizarre weather change scares them away. Raghava brings home his cricket stumps, which have been stained with blood from a buried corpse in the ground. He focuses on wooing Priya, his sister-in-law's sister. In the following days, his mother and sister-in-law witnesses several paranormal activities at night because of a ghost. On consulting a priest, they perform three rituals to ascertain if the house is haunted and their suspicion turns to be true.

Raghava's mother and sister-in-law hire two priests to get rid of the ghost from their house. However, the priests are actually con men and escape after seeing the real ghost. That night, the ghost possesses Raghava, who begins acting increasingly effeminate, alienating himself from Priya and wearing women's clothes and jewellery. His family angrily confronts him and it is revealed that there are actually three ghosts who have possessed him: a violent woman, an Urdu-speaking Muslim, and a mentally disabled boy. Raghava's family hires an exorcist, who drives the spirits away from Raghava's body. However, the woman's ghost being trapped, reveals her past.

Past: Karthik alias Kanchana is a transgender woman, who was disowned by her parents, and was later adopted by a kind Muslim named Akbar Bhai, who has an intellectually disabled son. Regretting that she could not become a doctor as she intended, she adopts another young transgender girl named Krishna alias Geetha and works hard to support her financially.

When Geetha leaves to study medicine abroad, Kanchana buys a plot of land where Geetha intended to construct a hospital for the poor. However, the ground is unlawfully taken by the corrupt MLA Shankar. Kanchana angrily confronts Shankar, but Shankar kills her, and also kills Akbar Bhai and his son. Before Kanchana died, she vowed to kill Shankar, his wife and his henchmen. The bodies are then buried in Kanchana's own ground.

Present: The exorcist sympathizes with her but remains duty-bound and traps her. After hearing her story, Raghava decides to help Kanchana, and allows her to possess him once again. Raghava/Kanchana confronts Shankar and disposes of his henchmen gruesomely. Shankar seeks refuge in a Narasimha temple, which Kanchana is forbidden from, but she asks the deity for justice and manages to chase him inside the temple. The three spirits combine and kill Shankar.

A few years later, Raghava has constructed the hospital for Geetha as per Kanchana's wishes. He also unites with Priya. A few local goons, who came there to demand money, becomes scared when Raghava is possessed again by Kanchana, implying he will be possessed every now and then when needed help.
