The film begins with a car chase in Chicago, which leads to a scuffle between a man ostensibly named Jude Rosario and an American male known as Matthew Brody. The scuffle ends with Brody falling into the icy waters of Chicago River, and his body missing. This results in Rosario being arrested and convicted for murder.
A flashback to six months prior shows the office of the Indian RAW chief Roy, where he and his trusted men and (Mohammed Zeeshan Ayyub) plan a daring covert operation. The man, known as Jude Rosario in the opening sequence, is shown to be Captain Daniyal Khan, a dead-end ex-soldier with a completely deadpan sense of life and death who is pulled out of oblivion and pressed into service by the spy agency to wreak vengeance on the men who planned the 26/11 Mumbai terror attacks. He agrees on the assurance that he will be reinstated in the Indian army to the same rank from which he was court-martialled, which meant regaining the respect of his estranged father, retd. Col. Usman Khan, and mentor, Dilawar Singh. His only team member, Nawaz Mistry (Katrina Kaif) helps him find his first target Sajid Mir at a cricket match in London. On reaffirming his identity after breaking into his apartment, Daniyal rigs up an explosion which kills Sajid, which makes the headlines explaining it was accidental, resulting in an investigation by the Pakistani ISI.
In present day, Daniyal aka Jude has landed in the same jail as David Headley, his next target. He contacts Nawaz in order to acquire money to buy a battery, as a replacement of another one which holds a certain poison. The poison, (succinylcholine), is untraceable as it can kill a person when it touches the tongue, causing a heart attack. After killing Headley by plugging the poisonous battery into a showerhead he usually uses, Brody, who supposedly died upon falling in the river, is found alive and Daniyal is released as his earlier sentence is rendered null and void. Meanwhile, ISI agents gather information about him.
Daniyal and Nawaz travel to Syria via Lebanon, to get in touch with the fighters of Lashkar-e-Toiba. There, Daniyal is held captive by the L-e-T and is forced into revealing the purpose of killing Sajid Mir and David Headley, on camera. The chief of L-e-T in Syria tries his best to send the video of Daniyal’s confession to ISI, but the war-torn situation of Syria has led to mass disruption of communication networks. Nawaz, with her team of soldiers, kills the subordinates of L-e-T, much to the chagrin of Daniyal. Subsequently, Daniyal, Nawaz and the team escapes from the clutches of the L-e-T after a bloody gunfight. Daniyal manages to kill the Syrian chief of L-e-T, just before he is about to send the video to the ISI, and destroys the recordings. Subsequently, the ISI kills the Indian Consulate General of Jordan, Mr. Rajan Sampath in a gas explosion, similar to the killing of Sajid Mir, as a revenge attack. The RAW chief Roy reprimands Daniyal for unnecessarily killing someone who was not meant to be killed and asks him to call of the mission. Nawaz encourages Daniyal to carry on the mission to avenge the 2008 Mumbai Attacks by killing the direct people who orchestrated the whole mission. She offers to take him and herself to Pakistan.
Daniyal and Nawaz, through Syria, go to Pakistan to take down the last two perpetrators, Sahabuddin Umvi and Haaris Saeed . There, they make plans of killing Saeed with the help of a local restaurant owner and RAW agent Khalid, by an explosive planted in the mic used during his public rally. However, their plan fails, leading Daniyal to pursue Saeed in a car and shoot him dead, also causing an explosion. Umvi is killed with the help of a nurse Amina Bi, a mother who lost her militant son in a suicide attack, who replaces his regular medicine with poison, later shooting herself after the police find her at her home.
With the Pakistani army and ISI pursuing them, Daniyal and Nawaz make their way to the coast to escape through the Arabian sea. Their accomplices get caught and interrogated for information or be killed. While they are escaping on a boat, the Pakistani military finds out about it and sends patrol boats to apprehend them. While hiding in the waters with Nawaz, Daniyal gets shot by the military and dies. Nawaz later gets rescued by the Indian Navy, after they leave. Later, she goes to the Taj Hotel and has two cups of tea, fulfilling a promise earlier made to Daniyal.
