Set in the early 2000s,
Ground Zero follows
BSF Second-in-Command (2IC) Narendra Nath Dhar Dubey (
Emraan Hashmi), who is tasked with dismantling a growing terror network in
Kashmir. The film opens with the rise of the “pistol gang,” a group of radicalized locals responsible for targeted killings of security personnel in
Srinagar, resulting in 70 deaths. Dubey's team regularly intercepts coded radio communications from the gang, which they manage to partially decipher. When his team deciphers a code suggesting a plan for an attack in Delhi, the
2001 Indian Parliament attack soon follows. The terrorist group
Jaish-e-Mohammed, led by Ghazi Baba, claims responsibility. The
Intelligence Bureau identifies Tariq Malik as a suspect linked to the attack and traces him to Srinagar. The IB arrives in Srinagar and requests the BSF's assistance in arresting him. Dubey suspects that Jaish-e-Mohammed and the pistol gang may be connected, based on the intercepted code and the fact that a Jaish-e-Mohammed terrorist is heading to Srinagar after the attack. He proposes monitoring Tariq instead of arresting him immediately, hoping Tariq will lead them to the top leadership of both groups. However, due to political pressure, the IB and Dubey's superior reject the idea. Dubey follows orders and arrests Tariq. Continuing his investigation, Dubey learns that some pistol gang members might be from local colleges. He deploys his officers to these colleges and manages to capture one militant, Hussain, after Hussain attempts to attack him. Dubey then successfully turns Hussain into an informant. Under Dubey's instructions, Hussain leads them to Hakeem, the pistol gang's doctor, and secretly plants a voice recorder inside his medical kit. Through this recorder, Dubey overhears a conversation between Hakeem and his superior—who turns out to be Ghazi Baba. Ghazi Baba is currently in Srinagar and discussing another planned attack in Delhi. Realizing this is a rare chance, Dubey attempts to apprehend Ghazi Baba without backup, but Ghazi Baba realizes what is happening, kills Hakeem, and escapes. Dubey brings his findings to the IB in Delhi, but the IB director dismisses the information, citing intelligence reports claiming Ghazi Baba is in Pakistan. However, IB officer Aadila (
Zoya Hussain) believes Dubey and orders a full-scale search in Delhi, hoping to prevent the attack—only to be shocked when the attack occurs instead at a temple in Kashmir. Facing nationwide outrage, the Indian government attempts to restore public confidence when the Prime Minister announces he will visit Kashmir. Jaish-e-Mohammed plans an assassination attempt during the visit, which security forces anticipate. Dubey is assigned to lead the PM's security detail. During the PM's visit, the convoy is ambushed by Jaish-e-Mohammed. A car rams into the convoy and its occupants open fire, killing several officers. Dubey's team protects the PM and captures one terrorist alive. During interrogation, the terrorist claims he is a sewer worker coerced by Jaish-e-Mohammed and knows nothing about the group. Dubey notices inconsistencies and calls out his lies. The terrorist then confesses, confirming Dubey's earlier intelligence: the original plan was an attack in Delhi, but once the leak was detected, they shifted the operation to the temple in Kashmir. He also reveals the location of Ghazi Baba's wife. Dubey's team tracks Ghazi Baba's wife and discovers the group's hideout. Dubey requests permission from his superior to raid the building, but the request is denied because only Ghazi Baba's wife—not Ghazi Baba himself—has been seen there, and the building is in a sensitive residential area. That night, Dubey and two of his officers, Binu and Praveen, defy orders and launch the raid. A fierce crossfire erupts. Ghazi Baba is indeed present. Praveen is killed in the gunfight. Despite being gravely injured, Dubey manages to kill Ghazi Baba. ==Cast==
