The film begins with happening in the cornfields in a village in South India, where a British forest ranger, who is in charge of the fields, has been alerted by some strange noises coming from deep inside the fields. He sets out with his dog and searches for the source of this strange noise, then suddenly the dog is being dragged inside and brutally killed by an unknown beast creature. Then, the forest ranger is also dragged inside and killed by the creature. Then the film shifts to the 1970s, where a college farewell party for Sir Arthur Wellington College is taking place. Two college friends, Amudhan and Vendhan, who is the son of the alcoholic college watchman Vethagiri, have decided to stay back in the college hostel and spend the vacation there.
