Duryodhan, Dushyasan and Shakuni plan to send the Pandavas to Varnavat. Shakuni provokes Duryodhan to continue insulting Bhishma. Gandhari becomes shocked on learning that Duryodhan wants Dushyala to marry Jayadrath, the King of Sindhu.

Shakuni becomes delighted on learning about the success of his plan against the Pandavas. He informs Duryodhan about his plan against Kunti. Vidura warns Yudhishthir about Duryodhan's conspiracies. Meanwhile, Karna is shocked to learn about Duryodhan's plan to kill the Pandavas.

Seeing Karna's reaction, Duryodhan pretends to be furious at Dushyasan and asks him to call off the plan against the Pandavas. Kunti and the Pandavas leave Hastinapur for Varnavat. In Dwarka, Lord Krishna asks Arjun to bathe in the Triveni Sangam, on their way to Varnavat.

Vidura decides to spy on Karna to know the Kauravas' plans. Later, he learns the truth and decides to inform Bhishma. Kunti and the Pandava brothers reach Varnavat. Purochan lies to them about the palace. Kunti wishes to light a lamp in the palace. But instead of the lamp, the floor catches fire.

Vidura sends a mouse inside a rice bag to the Pandavas. They are shocked and wonder what Vidura is trying to telling them. Duryodhan assures Shakuni that Karna will not interfere in their plan. As Bhishma leaves for Varnavat, Shakuni changes the plan and sends a message to Purochan.

On receiving Shakuni's message, Purochan decides to set the palace on fire. Purochan also poisons the sweet dish. To test the sweet dish, Bheem takes it to the mouse. Arjun understands Duryodhan's plan when he discovers that the palace is built of lacquer. How will the Pandavas save themselves?

Just when Kunti is about to eat the sweet dish, the Pandava brothers see the dead mouse. Kunti becomes sad on learning about Duryodhan's plan and informs her sons that they will not return to Hastinapur. But if they stay in the palace, they will get killed.

Purochan sets the palace on fire. Bheem suggests that Arjun should use Varunastra to stop the fire. However, Arjun thinks they should escape through an underground route. The Pandavas begin digging a tunnel to escape. Bhishma reaches Varnavat, only to see the entire palace in flames.

Bhishma finds the burnt weapons of the Pandavas in the ruined palace. He assumes they are all dead. On his way back, he immerses the burnt weapons in the Ganga. Later, the Pandavas and Kunti emerge from the tunnel. They decide to live in disguise, before returning to Hastinapur.
