The film starts with a group of college students enjoying a picnic in a forest in Ooty. One of the girls, Nisha (Mink Brar), dies under paranormal circumstances. She had inexplicably attacked her boyfriend like a monster and was rushed to the hospital, where just before dying, her face and voice changed completely, confusing the doctors. Professor Agni Swaroop (Ashutosh Rana), who is supposedly an expert in the supernatural is called by police to look into the matter. After investigating, Swaroop declares that she was attacked by an evil spirit. He reveals that this spirit has awakened for a purpose and will not stop until that purpose is fulfilled.
The story turns to Sanjana Dhanraj (Bipasha Basu) and Aditya Dhanraj (Dino Morea) in Mumbai, where, during a business party, Aditya seems too busy to pay attention to his wife. She leaves the party and on her frantic drive home, she hears a voice in her head and loses control of the car. She manages to escape the accident unscathed. After her recovery, Sanjana asks her husband for a divorce; Aditya, however, realises his fault and suggests a vacation to work out their problems. Sanjana chooses to return to Ooty (where their relationship first began) to save their failing marriage. They stay in the same bungalow behind which Nisha was attacked. Initially, the couple enjoys their stay but Sanjana starts experiencing mysterious things, such as hearing a woman screaming in the forest. On the other hand
Aditya brushes her concern away blaming it all on the sleeping pills that Sanjana is addicted to. From another cleaning staff who visits the house on Aditya’s order, she learns that their previous caretaker Robert has not been visiting the home to clean and has disappeared without a trace. Sanjana decides to visit Robert’s wife who tells her that he changed and became scared whenever anyone used to mention the guest house. She also told her that he used to hear strange voices from the forest, just like Sanjana, and then suddenly disappeared one day. With the help of their friends, Aditya and Sanjana reconcile.
