But Narayanan's son is furious that Sathyamoorthy had bashed him and tries to kill him but he himself is killed. Sathyamoorthy decides to join Rowdy Veeramuthu's gang to finish rowdyism.

In a final election meeting, Sathyamoorthy snaps up from paralyzed state and lectures people on electing good unselfish leaders. He is arrested for his deeds and Veeramuthu is also arrested.
In a parallel comedy track, Anjukolai Aarumugam (Goundamani) is feared as he has killed five people. But in reality he had stolen five coconuts.
