AI scientist Dr Bhargav's abduction from a tech summit and a senior R&AW officer's killing in Delhi push Himmat Singh to realise the beginning of a silent war.

Probing Chaddha and Banerjee, Himmat learns about Shekhawat's mission. Subramanyam pressures Himmat to grab a bank defaulter. Farooq goes to Athens to locate another AI scientist.

Avinash finds a critical lead in Budapest. Himmat learns that the attacks are part of a covert cyber war by China and a larger digital offensive designed to destabilise India.

Avinash and Juhi head to Dominica to trace Jignesh Dholakia, who Subramanyam wants arrested at any cost. Meanwhile, Himmat's daughter, Pari, finds long-buried secrets.

As the web tightens, Himmat suspects a mole within, which leads him to the Collector. Meanwhile, Abbas is tasked with digging into Subramanyam.

Himmat pieces together the identity of Sudheer Awasthi, who is pulling the strings of the imminent cyber warfare. Later, he finds the mole leaking internal information.

With the clock ticking and the nation hanging by a thread, Himmat and his core squad brace themselves before Sudheer's final phase goes live with the help of Dr Bhargav.
