The story begins with a young couple, Balu and Ishwarya, being chased by some goons. Ishwarya is the daughter of Rajadorai (Charan Raj) and had eloped and run away with her boyfriend Balu against the wishes of Rajadorai. Rajadorai sends his goons to track down the couple. When the goons finally track down the couple in a forest and start beating up Balu, a man (Rajinikanth) comes to the couple's rescue. When Rajadorai and his brother Ramadorai (Nizhalgal Ravi) find out about this man, they rush over to his hideout in the forest, only to escape in fear when they see him. The couple is scared and puzzled as to how the man could induce so much fear in the brothers. The man's wife Parvathi (Gouthami) then tells the couple the story of the man, whose name is Dharmadorai.
