Republic forces launch a bombing attack on US ships stationed near a NATO camp in the Pacific Ocean. The strike sends petrol prices soaring to Rs.500 per liter and fuels a sharp rise in geopolitical tensions. The event marks a turning point in naval power and global trade disruptions.

Nataraj, the kingmaker of Tamil Nadu, compels his bedridden brother-in-law's daughter Keerthana to enter politics and secures her a post as Education Minister. Her ascent shifts state politics and alignment ahead of elections. Thamizharasan, an orphan she had met during a trek, guides her toward a new education policy that wins broad public support.

Tamil Nadu police arrest the state's opposition leader before the CBI can act, aided by Nataraj and Union Finance Minister Ramakrishnan, nicknamed Central Ramki. Containers holding black money in Republic currency are found at the Chennai Harbour, triggering a fresh political firestorm. The move consolidates power for the Republic-aligned camp while provoking protests across the state.

A riot at Puratchi Veeran Pulipandi's meeting spreads across Tamil Nadu as police clampdown escalates.

Central resistance weakens as security powers tighten their grip.

Through Prakash Amudhavanan, Nataraj learns that Thamizh was a UN anti-poaching gun marshal and orders his killing. Major Prabhjoth Singh arrests Nataraj in connection with squandered black money, deepening the conflict between state power and Republic operations. The arrest sets the stage for a brutal political and military confrontation.

On February 15, 2029, air strikes hit Delhi, Ahmedabad, and Mumbai, and nuclear radiation disrupts ISRO's space link. Chennai endures heavy bombardment as Republic troops infiltrate Tamil Nadu.

In the Masinagudi hills, the escaped Thamizh leads a hidden camp while Nataraj awakens from a coma and reunites with Pulipandi, Prabhjoth, Dass, Perumal, and others under Thamizh's leadership. They uncover aluminum mining intended for Republic communication antennas and vow to resist the occupiers. The camp becomes a nexus of renewed resistance in the region.

Thamizh, Nataraj, and Prakash Amudhavanan execute a final three-pronged assault on the Republic camp, using decoys to mislead pursuers. They capture Priyanka, kill General Tso, and rescue GNR, while Pulipandi is detained and the torture camp is neutralized. A mid-credits reveal hints that AI robots started the war, signaling a new era of conflict.
