Kaatteri

The film begins with a 1968 local village festival. One person cuts an electric post, another person comes and pushes down the post, and the electric wire rips all of the village people.

The film cuts to 2019. Gajja, Kaliyurunda, and Sankar, a group of kidnappers, kidnap Kamini and bring her to Naina. Naina orders his henchmen to kill the kidnappers so they cannot tell anyone about it. The kidnappers escape from the henchmen, come to Kiran's first night room, and tell them about the kidnap and Naina's plan to ask for a huge ransom from Kamini's family. Kiran's wife Shwetha instructs them to kidnap Kamini from the henchmen and demand a large ransom.

As per her instruction, Kiran and his friends kidnap Kamini and ask her about Maanga Mani. Kamini tells them about him. He was taking a treatment from her, and a few weeks ago, he said he was about to go on a treasure hunt for gold. Shwetha finds Maanga Mani's location by entering his number on Truecaller. They went to the same location that was shown on Truecaller. The village's name is Kolaatipuram. When they enter the village, the behavior of the villagers is weird, and they realize that the villagers are ghosts. They are the people who died in 1968. After knowing that the villagers are ghosts, they try to elope from the village, but they cannot escape from there. Wherever they run, they end up in the festival area. Kamini tells them that Sankar was taken by a ghost, Mathamma, who asked her, "Am I beautiful?"

Shwetha instructs them to meet Maathamma and correctly answer questions in order to obtain the gold, so they walked to Mathamma's place. Shwetha ran away after seeing Mathamma, and Kiran and his friends got beaten by Mathamma. Mathamma tells her story, which happened in 1968. She, her sister Mohini, and her uncle Venu were living in the same house. Venu tells a well digger Sambath to dig a well at the back of their house and orders Mohini to help him. While digging the well, the land slides and the well becomes too deep. Sambath gets out of the well with Mohini and Mathamma's help. He requests that they bring a lamp to measure the depth of the well. They tied a rope around the lamp and put the lamp into the well. When they pulled up the rope, the lamp was missing, but a mud pot was tied with the rope. When they opened the mud pot, the pot was filled with gold jewels. By seeing this, Sambath tells them he is going to buy more lamps to get more gold.

After Sambath leaves, they discover a piece of paper with the words, "If you have anything else, send it to me." So they take a chicken and throw it down the well, and this time they get a large mud pot filled with gold and a piece of paper with the same message as earlier. Sambath came back with a lot of lamps, and he put all of them into the well, but when he pulled the rope, all the lamps were damaged. When he saw the damaged lamps, he became angry, and took an aruval, and entered the well tied up with a rope. When Mathamma and Mohini pulled the rope, a big wooden barrel appeared with a paper written with "Keep sending this to me". By seeing the paper, they send their drunkard uncle Venu into the well. They understood that the well needed human flesh, so they ask Aarumugam, a police officer, for dead bodies, which he gave. One night, Aarumugam enters the house of Mathamma and sees a lot of gold. At that time, Kaatteri came out of the well, ate one of the policemen and wrote on the wall, "Do not starve the well". By knowing this, Aarumugam planned to kill all of the villagers and feed the Kaatteri. During the festival, he cuts the electric post, and the wire rips the people. They put all of the dead bodies into the well. He also pushed Mohini and Mathamma into the well.

Mathamma's story ends, and she asks Kiran to tell him which part of her story was fact and which was fiction. Suddenly, Kamini behaves abnormally, and her face changes to Mohini's. Ponnambalam comes to the house and asks Kiran to burn Kamini. Kiran burns her, and Ponnambalam captures Mohini's ghost. When Kaatteri comes to kill them, they try to manage and save their lives. By luck, they managed that night, and then Ponnambalam tried to kill Kiran while running after him. Unfortunately, he fell down, shot himself in the chest, and died. Kiran took the bottle that has Mohini's ghost in it and gave it to Naina. Naina opens it and gets frightened by seeing the ghost.

The film ends with Kiran and Shwetha in bed, where Kiran asks Shwetha about how she knows that Aarumugam is Naina, and Shwetha asking him, "Am I beautiful?"
