Tiger3

Avinash "Tiger" Singh Rathore is called for a mission by R&AW chief Maithili Menon to rescue Tiger's former handler Gopi Arya from the Taliban in Afghanistan, who was captured after trying to extract information about a mission being planned in Pakistan. Following his rescue, Gopi reveals that Zoya is involved in the planned mission and dies shortly after. Tiger begins to spy on Zoya, where he is assigned to safeguard a RAW agent named Jibran Sheikh in St. Petersburg, Russia, who worked with Gopi and escaped to the country after being discovered in Pakistan. Tiger witnesses Zoya's attempt to assassinate Sheikh; after saving him, Tiger is captured by Zoya's protège and former ISI agent Aatish Rehman, who reveals that he forced Zoya to assassinate Sheikh by nearly fatally drugging and kidnapping her and Tiger's son Junior.

Tiger and Zoya recruit their team of RAW agents, consisting of Rakesh Prasad Chaurasia, Nikhil and Karan Rao; to steal a briefcase for Aatish, containing missile launch codes in Istanbul in exchange for Junior. Aatish then has Tiger and Zoya framed as terrorists and traitors by their respective countries, leading to Tiger's imprisonment in Pakistan. It is revealed in a flashback that Aatish sought to derail a peace treaty between India and Pakistan in Vienna in 2011 by assassinating the lead Indian army general twelve years earlier. After refusing to cooperate with the plan, Zoya covertly informed Tiger. Aatish's pregnant wife Shaheen Baig, attempted the assassination, but was shot and killed by Tiger. Aatish denied that his agents know about the plan and was subsequently imprisoned and ousted from the ISI.

Tiger is sentenced to death, but manages to escape from the army prison in northern Pakistan with the help of Pathaan. Tiger travels to Islamabad where he meets his adopted son, Hassan, a former child soldier turned hacker whom Tiger had rescued during the Ikrit mission. Tiger's team, Zoya and ISI agents Abrar and Javed return to Istanbul, where they learn that Aatish and Pakistani Army General Imtiaz Haq are planning to assassinate Pakistani Prime Minister Nasreen Irani in order for Aatish to replace her. Tiger, Zoya, and their team secretly enter the PMO and reveal the plan to Irani. Tiger and Zoya take Irani to an underground bunker and Tiger forces Haq to publicly reveal the plan.

However, Aatish secretly kills Haq with the help of Javed, who is revealed to be Shaheen's brother and frames Tiger for killing Haq. Abrar and Karan are killed by Aatish and Javed, who locate Irani. Hassan sacrifices himself to create a diversion, allowing Tiger and Zoya to help Irani escape. Zoya later avenges Abrar and Karan by killing Javed. Tiger kills Aatish, while Irani exposes Aatish's plan to the public. Tiger, Zoya and their team are proven innocent. Rakesh and Nikhil's charges are dropped by Menon while Tiger assures her that he will return to serve his country on his own terms.

In a post-credits scene, Colonel Sunil Luthra contacts Kabir Dhaliwal and assigns him to assassinate an unidentified person.
