But Netra is drowned by goons, when he tries to reach their den which is hidden under water. Disappointed at his failure, Satyanarayana sends in another agent Vijayasanthi to investigate Netra's incomplete mission. She lands up in the village where Netra was drowned in water but finds a man who has an identical vehicle appearance as Netra (who is actually Netra himself.

He saves her from drowning when she tries to explore the hidden den under water and unwraps his disguise to reveal how he escaped from drowning. They both reach Malaysia trying to reach the roots of the underworld.
