Kabir

The film opens with a series of bomb blasts in Mumbai, creating immediate fear and drawing investigators toward a possible Indian Mujahideen link. Authorities scramble to piece together the network and motive behind the attacks. This violent start sets the tone for a high-stakes pursuit throughout the story.

A burkha-clad Yasmin departs Zaveri Bazaar in a taxi headed for VT station, but the ride turns tense when the driver refuses to continue. After a brief standoff, another car stops and Abir Chatterjee offers her a lift. She senses danger even as she accepts the ride.

On the way to VT, Yasmin talks to her half-paralyzed father in Kolkata, who is watching news of the Mumbai blasts. Abir reveals he is also bound for VT, and she begins to learn more about him. The uneasy rapport between them deepens as the journey continues.

At VT, Yasmin discovers the Duronto Express is delayed by about two hours, forcing her to wait in the upper-class lounge. She unexpectedly encounters Abir again, and they end up in the same Howrah-bound compartment. The stage is set for a dangerous game of lies and revelations.

During the journey, Abir flirts with Yasmin before revealing a chilling live video showing her father hostage and a cousin in danger. He threatens to kill them unless she reveals Imtiaz's location. Her attempts to contact friends fail, heightening the peril she faces.

Abir declares he is a jihadi and explains that many passengers in their compartment are his aides. He claims Imtiaz betrayed them in 2012 and must be murdered. Yasmin's stance shifts as she is drawn into a web that suggests she herself could be a jihadi, and Abir changes his name to Altar Kabir.

Kabir, now calling himself Altar Kabir, dismisses Yasmin's version and insists on his own narrative. Frustrated, she contacts Syed, Indian Mujahideen's third-in-command, using a coded reference to Kabir to leak information. The train's claustrophobic space elevates the tension between loyalty and betrayal.

Meanwhile, police officers begin decoding the coded clues from Yasmin's signals and manage to trace Syed through her communications. The net tightens around the IM network as investigators close in on their target. The train becomes a battleground of wits and surveillance.

Kabir discloses his real identity as a special task officer tasked with dismantling the Indian Mujahideen gang. The reveal reframes all prior interactions as part of a coordinated operation rather than a random encounter. He uses his undercover status to steer the confrontation toward a controlled outcome.

Yasmin argues that arresting her would simply pit police against IM leadership, who would trade hostages for her handover. Kabir grasps the strategic implications and recalibrates his plan to prevent further bloodshed. The clash tests both their loyalties and the ethics of the operation.

In a dramatic turn, Kabir moves to neutralize the threat, resulting in Yasmin's death. He shoots as if to defend himself and to protect the mission, all while concealing his true identity. The violent climax marks a brutal twist in the undercover operation.

The film's arc culminates with the National Investigation Agency pursuing Indian Mujahideen co-founder Yasin Bhatkal near the Indo-Nepal border. The operation underscores a broader crackdown on the network beyond Yasmin and Kabir’s narrative. The ending ties the personal mission to a wider campaign against terrorism.
