Avantika, a psychology professor, returns to Delhi to care for her ailing father and soon meets Ehsaan Khan, a university lecturer. They form a deep bond, fall in love, and marry shortly after. The marriage signals the start of their plan to relocate and build a life together.

The couple relocates to a quiet suburban neighborhood in the United States. Avantika helps Ehsaan secure a teaching position at the same university, where he begins lecturing on Islam and the Modern World. Their move marks a transition to a multiethnic, tightly knit community.

Avantika befriends Salma, who confides that her husband Hakil keeps her confined at home. Salma pleads with Avantika to contact Rehana, a television journalist. Avantika introduces Rehana and Riyaz, and they discuss plans to help Salma.

Rehana plans to join a United Nations envoy and leave for Iraq, signaling escalating danger. Around this time, Avantika's circle becomes aware of a broader plot and the risks surrounding Salma. The conversations hint at a dangerous network behind Salma's predicament.

Avantika discovers she is pregnant, adding emotional weight to the danger surrounding Salma and Rehana. She must navigate fear while keeping up appearances in her new life. The pregnancy raises the stakes for both her safety and the family's future.

While walking near her home, Avantika overhears Bhaijaan leading a meeting about bombing Rehana's flight. She also discovers Salma's body, which confirms the threat is real. The group pursues her, forcing her to flee to her home for safety.

Back at home, Avantika learns that Ehsaan is part of the terrorist cell and had married her to gain US residency. Bhaijaan orders Ehsaan to kill Avantika, but he spares her life because of the pregnancy. The revelation confirms the double life she has entered.

Ehsaan confines Avantika and threatens her father to ensure silence. She records a voicemail warning Rehana, but Rehana's flight is bombed, killing everyone aboard. The personal danger now extends to the public event she had hoped to influence.

Riyaz, devastated by Rehana's death, finds Avantika's message and begins investigating the network. He enrolls in Ehsaan's university course and gradually earns his trust, moving closer to the inner circle.

Aapa, Bhaijaan's wife, explains the motivations behind their ideology and reveals Ehsaan's past as a man radicalized after his family was killed in Afghanistan. Her account widens the perspective on the group's grievances and aims. The revelations shed light on the roots of their movement.

Ehsaan and Hakil attempt to dispose of Salma's body, drawing police attention. Ehsaan kills Hakil and the officers; Salma's remains are recovered and disseminated through the FBI. The investigation tightens and strands the group in fear.

Ehsaan introduces Riyaz to Bhaijaan, who tests him with a staged firearm scenario. Riyaz passes and is inducted into the next plot to bomb subway stations in New York.

Riyaz and Avantika collaborate to foil the planned subway attack. Riyaz schedules a meeting with the FBI, but Bhaijaan accelerates the mission after discovering Salma's identification.

During the chaotic operation, Bhaijaan is fatally shot; before dying, he reveals that additional explosives are hidden in the women's belongings, including Avantika's. Ehsaan races to rescue Avantika as the FBI intervenes and retrieves the explosives. Ehsaan kills Aapa and saves Avantika.

In the final moments, Ehsaan reveals his real name, Khalid, to Avantika. He professes his love before taking his own life, dying as they escape the danger together.
