After their father's murder, IAS aspirants Ajay and Nannu want to avenge his death. Mamta, their mother, prepares them to rule the liqour mafia of Bihar and become more powerful than Babban.

Babban appoints Shankar to find Balli's murderers. Mamta introduces Ajay and Nannu to the world of country liquor mafia. The siblings take over the trade and get ready for a face off with Babban.

Smart-witted and swift, Ajay and Nannu soon move up the system in the liquor business. However, they are unaware of Babban plans to destroy them instead.

An all-new guest enters Mamta's home, but he has a grave mission to fulfill. ACP Arun plans to catch Ajay and Nannu red-handed while at their job.

While the war to take revenge results in Babban's Den being destroyed by the two siblings, Babban seems to have bigger plans to bring Mamta and her children down.
