During the post-Kargil period, Heena Rehman is killed at a party hosted at Minister Mirza's house. The murder shocks intelligence circles and raises questions about who manipulates whom. This event triggers RAW's deeper investigation into a mole leaking defense secrets.

Krishna 'KM' Mehra is devastated by Heena's death, realizing she was a RAW asset turned double agent. Jeev informs KM that there is a mole in RAW leaking sensitive information, setting KM on the path to hunt the leak. The sense of betrayal fuels KM's resolve to protect India's secrets.

KM and her team scrutinize Ravi, a RAW employee whose lavish lifestyle doesn't match his income, raising suspicion. KM suspects Ravi's wife Charu as an accomplice, and they obtain permission to bug Ravi's house to monitor his activities. The search widens as surveillance begins.

Surveillance uncovers that Ravi is working for the CIA at his mother's insistence, while Charu remains unaware of her spouse's double life. The revelation redirects the investigation from Charu to Ravi's true allegiance. KM's team adjusts their strategy to track Ravi's transactions and contacts.

Jeev explains that Heena's death was entangled in higher-level politics: the Minister of Home Affairs had to disclose information to the CIA to prevent the US from scrapping the nuclear deal with India. He urges KM to keep this wider context secret to avoid destabilizing the alliance. The moral cost weighs on Jeev as he contemplates keeping intelligence from his own team.

Ravi discovers that his every move is under watch and makes an attempt to flee with his family. Charu refuses to join him or relent, prompting Ravi's mother to shoot Charu, though Charu survives. KM's team arrives just in time to secure Charu and rush her to the hospital. The family crisis deepens as loyalties and truths unravel.

After recovering, Charu learns that Ravi has taken their son to the United States and seeks to reclaim him. KM trains Charu and dispatches her to the US to retrieve her son, providing a path for reunion and justice. Charu's mission becomes personal as she confronts her past and Ravi's new life.

In the US, Charu tries to blend back into Ravi's family and win them over by presenting herself as someone who simply wants the family back together. She navigates the tension between loyalty to KM and the dangerous web of Ravi's new life. Her ability to hide her true purpose tests her resolve and patience.

Flashbacks reveal KM's growing feelings for Heena and the truth she discovers about Heena's double life as an ISI asset while appearing for RAW. Heena argues that she joined ISI only to extract information for RAW, a claim KM struggles to accept. Heena volunteers for a suicide mission to kill Brigadier Mirza, but the plan is foiled when Ravi informs the CIA, which informs Mirza, leading to Heena's death.

Ravi and his family, living as refugees in South Dakota, are persuaded by KM to return to India as heroes if they help eliminate Mirza. During Mirza's visit, Ravi and Charu's family attempt to poison him, but Mirza senses the trap and kills Ravi's mother. Ravi strikes Mirza and knocks him unconscious, while KM has the CIA's psychiatrist doctor stage Mirza's death as an accidental bathtub incident.

With Mirza 'dead', Ravi and his family are deported back to India and begin anew. KM arranges for them to be seen as heroes who helped protect India's interests, though the truth of the mission remains buried. The twist underscores the cost of loyalty and the shades of loyalty in intelligence work.

At Charu's urging, KM reaches out to her estranged teenage son to reveal the real reason behind Charu's divorce: her sexual orientation and truth about her relationship. The scene hints at deeper family consequences and sets a note of personal resolution for Charu and KM's storyline.
