Puli (Vijay (actor)) is the adopted son of a tribal village chief Vembunathan (Prabhu Ganesan). From a young age, he notices the atrocities regularly committed on the villagers by a group of people from the neighbouring kingdom of Vedhalapuram called the Vedhalams, who have supernatural powers. When he becomes an adult, he starts to protect the villagers from the Vedhalams, because of which he is well respected by the villagers.
