An assassination attempt on the Viceroy shakes the foundations of the British Raj. As the Empire unleashes the ruthless Lt. Col. Dyer to hunt down those responsible, Rash Behari Bose races to finish the mission he set in motion. Sachindranath Sanyal struggles against his family's legacy of operating in the shadows, throwing his engagement to Pratibha Lahiri into question.

After a narrow escape, Rash contemplates his next move. Sachin is torn between the promise of love and his dream of fighting on the frontlines of the freedom struggle, facing a choice that could alter the course of his life. Meanwhile, Dyer's relentless investigation for British India's Most Wanted Man leads him to Benaras.

Rash and Sachin reunite with Pishima, caretaker of the Revolutionaries' Calcutta safe house. After years underground, the legendary Bagha Jatin returns with an audacious plan: to execute the greatest heist the British Empire has ever seen. DCP Tegart closes in on the elusive revolutionary and, determined not to let Jatin slip away a second time, unwittingly walks into a carefully laid trap.

The Revolutionaries go underground. As Dyer tightens the noose around Rash, an unforeseen obstacle throws his hunt into disarray. In Benaras, 18-year-old rebel Kartar Singh Sarabha joins forces with Pratibha, who takes a bold risk to deliver a message that could alter the rebellion's fate. And when a message from Ghadar leader Lala Hardayal reaches Rash, a dying revolution surges back to life.

A devastating incident leaves Rash and Jatin confronting the cost of their cause, as Sachin fights for his life. Just as Dyer narrows in on the hiding Revolutionaries, the tide begins to turn, as thousands answer the call of revolution.

After a long and perilous voyage, the Komagata Maru finally docks in Calcutta. Disguised among the crowds, Rash, Kartar, and Pishima arrive to receive the revolutionaries returning home to fight for freedom. But the British are ready for them. As Dyer and Tegart race to unravel the insurgent plot, Rash finds himself trapped at the heart of a conspiracy on the verge of exposure.

An ally and a mole are both revealed. Pratibha challenges Jatin's perspective on the role of women in the revolution as Pishima holds on against torturous circumstances. The Revolutionaries scatter to execute their plans, leaving themselves dangerously exposed. Meanwhile, Tegart pieces together a single, devastating clue that could bring the entire revolution crashing down.

Heartbreaking news months before Ghadar day leaves the Revolutionaries reeling and forces Rash to confront the terrible cost of freedom. When all hope seems lost, Pratibha arrives at the training camp with a bold plan that could save the rebellion. But as the dream of revolution is reborn, the mole finally plays his cards, threatening to bring the entire movement crashing down.
