In 1995, a man explains to his four sons the philosophy of not desiring another person's possession by citing the 'Thirukural' poem as an example. When Raja finds a letter addressed to Mr. Sakthivel, he and Rajini reach the location to hand over the letter to him. Instead, the letter is received by his brother, Mr. Rajavel. But the contents of the letter force Raja and Rajini to set out on a path to find Mr. Sakthivel.
