Nakul informs Arjun of Abhimanyu's killer. Arjun decides to kill his son's murderer and heads for the Kaurava camp. He attacks the Kuru soldiers, but Yudhishthir stops him from proceeding further.

Krishna covers the sun with his Sudarshan Chakra to protect Arjun from the Kaurava army. Later, Arjun uses the Pashupatastra to destroy his son's killer. Shakuni suggests Duryodhan should attack the Pandavas at night so that Karna gets an opportunity to kill Arjun.

To defeat the Kauravas at night, Krishna tells Bheem to ask Ghatotkacha to join the war. Karna decides to use his divine weapon against Arjun. Ghatotkacha creates havoc in the Kuru camp. Instead of attacking Arjun, Duryodhan instructs Karna to use his divine weapon against Ghatotkacha.

On Duryodhan's insistence, Karna uses the divine weapon presented by Indradev against Ghatotkacha. Bheem tries to save him, but fails. Ghatotkacha assumes gigantic proportions and falls on the Kuru army. Later, Karna accuses Krishna of using Ghatotkacha to exhaust his divine weapon.

Duryodhan humiliates Dronacharya for leaving the battlefield. Shakuni tricks Dronacharya and persuades him to stay. Later, Krishna tells the Pandavas to kill Ashwatthama, to make Dronacharya surrender. As Karna challenges Nakul and Sahadev, Arjun challenges Dronacharya to a fight.

Karna spares Sahadev's life on remembering his promise to Kunti. Bheem kills an elephant named Ashwathama. Dronacharya decides to destroy the universe when Yudhishthir tells him about Bheem attacking Ashwathama. Who will make Dronacharya realise the mistakes he made while bringing up Ashwathama?

As penance, Krishna persuades Dronacharya to sacrifice his life. Meanwhile, Dhrishtadyumna beheads Dronacharya. The Pandavas, Krishna and the Kauravas pay their homage to Dronacharya. Later, using the boon given to Gandhari, she decides to save Duryodhan's life.
