Thevalli decides to teach both of them the 3 Vedas in order to make both sons illustrious, taking the advice of his mentor Thirumeni.

He seeks out Mekkadan, and offers to become his disciple; they move on to a remote location and practice dark magic.

Later on Mekkadan dies, but Ananthan continues his studies, which leads to severe calamities and deaths in his village.

To put a stop to all this, Thevalli asks his younger son to meet his elder brother and dissuade him from destroying the village.

Vishnu, along with his friends, travels to the forests where the house of Ananthan is located, the tribals refusing to help them.

While Ananthan is away from his home, Vishnu and his friends enter the house and invoke counter tantric measures.

In spite of Vishnu's warning, when his friend removes the magical protection which saves the house from the destructive powers of nature, he is killed by an entity.

Usha awakens the destructive powers of nature when she places a circle inside a Tantric kalam.
