This thrilling tale sparks off with chilling scenes of a young woman, who travels to meet her parents, becoming possessed by a ghost.
Then, the scene shifts to casual conversation between five friends, who are in the process of planning for a holiday to Valparai. One of the friends, Aravind is initially reluctant to go, butlater agrees to have fun with his friends. They travel together, when one of his friends while clearing up his room visualize eerie things but he's too ashamed to tell his friends as he would be teased. They all reach Valparai and meet Valparai Varadhan, a useful contact who gets things done for them.
Ayesha, their friend Ram's girlfriend brings them dinner. As paranormal events begin to happen, the friends think that Krishna may be possessed by Ram, his dead brother. When they go to Aravind to tell him about Krishna, they come to know that it is Aravind who is possessed by Ram and not Krishna.
Ram narrates the story, telling that his friend Aravind promised him to get permission for Ram from his parents to marry his girlfriend Ayesha. His parents did not accept her as she is a Muslim. Aravind tells Ram and Ayesha to stay at Valparai for few days and by then his parents would accept.
One day Ram's parents make another arrangement for his wedding. But when Ram calls he says that convincing his parents can never happen as they dislike Ayesha. Then later Aravind receives a call from Rafiq that Ram has slit his hands and has committed suicide. In order to avoid Ayesha getting hurt, Aravind hides it from her and goes to Ram's house.
Ram possesses Aravind's body and expresses his wish to kill Aravind in order to exact revenge upon him. He says that he does not wish to harm anyone else.
The friends seek help from Valparai Varadhan and attempt to bring Aravind back. Finally, they reach the place where Ayesha lived and are shocked to see that she has already committed suicide after learning of Ram's death. It was her spirit who brought dinner for them.
On that day when they are about leave Valparai, they are confronted by Ram and Ayesha, Aravind says that he is ready to die for his friend and narrates his side of the story.
It was Ram's birthday, so to surprise him, Aravind had told him to come to a place. The place is then revealed to be the Register's office to get Ram and Ayesha married. Aravind wanted to surprise Ram by giving him a birthday gift – fulfilment of his dream to marry Ayesha. He mischievously lies to Ram that his parents will not accept Ayesha and tells him to stop spoiling Ayesha's life. Taking this seriously Ram commits suicide. Aravind feels sorry for him and asks to take his life but after forgiving him.
Ram says he either has to kill Aravind or he needs to live a life through Aravind. The screen goes blank and after few weeks, Aravind is engaged to the same girl who was possessed in the beginning which implies that Ram and Ayesha will live together with the help of Aravind and his wife.
