‘D Day’ movie is the first hand account of the incredible mission that is undertaken by the Indian secret services agents to capture the most elusive and most wanted man in India.
It starts off with agent Wali Khan (Irrfan Khan), appointed by the Chief of Indian intelligence agency Research and Analysis Wing (RAW), Ashwini Rao (Nassar), has been on a mission for nine years to keep an eye out for the activities of India's most wanted D-Company leader, Goldman (Rishi Kapoor). Ex-Indian Navy's Marine Commando and undercover agent, Captain Rudra Pratap Singh (Arjun Rampal), R.A.W.'s explosives expert, Zoya Rehman (Huma Qureshi), and Aslam, a Mumbai thief, were recruited by R.A.W. nine days before to infiltrate Pakistan and support Wali to apprehend Goldman, who is about to break protocol and attend his son's wedding.
On the day of the wedding, Wali sees his wife and son off at the airport, where they are meant to fly to London. Wali goes home and stages his family's death in the hopes that the ISI will not put them in harm's way. However, all flights to Europe are cancelled, stranding Wali's wife and son at the airport. When Wali's wife attempts to leave the airport, she is stopped by an ISI officer, who informs the ISI delegation at the wedding that something is wrong. As a result, Wali, Rudra, Zoya, and Aslam's plan to capture Goldman is placed in jeopardy. Goldman escapes unscathed and the four agents have to go into hiding. Embarrassed at the failure of their operation, the Indian government disavows the four agents; only Ashwini remains their ally, but he is forced to resign. Aslam is captured and tortured by Goldman's nephew. He is rescued by Rudra, who was trying to take revenge on Goldman's nephew for murdering Rudra's lover, a Pakistani prostitute. Upon hearing that Wali's wife has died and that his son is in ISI custody, the four agents decide to find a way to finish their mission, despite the government having abandoned them.
The ISI decides that Goldman is too much of a liability to continue protecting, so they decide to kill him. Before they can, the four RAW agents take out the ISI and take Goldman hostage. Wali notifies Ashwini, who works to find them a safe route out of Pakistan. Goldman taunts Wali by telling him that his wife and son are actually still alive, and that he can arrange their reunion. Wali is torn between accepting Goldman's help and finishing his mission, to the point where he shoots Rudra to take control of the group. Ashwini tells them to be at Check post 35 before 6am. At the same time, Wali arranges a meeting with ISI, proposing an exchange of Goldman for his wife and child. After tying up Rudra and disarming Zoya, Wali leaves with Goldman. Zoya then frees Rudra and they also leave.
Wali drives to Checkpost 40 but is shot and killed by Pakistani forces, who, unbeknownst to Wali, have poisoned and killed his wife and son. As Wali's car is examined, it is revealed that Wali did not actually bring Goldman with him; he had apparently anticipated the Pakistani betrayal, and had left Goldman in the car that Zoya and Rudra had taken. Through flashbacks, it is revealed that this was a plan hatched by Wali and Rudra in order to get Goldman to cooperate and give Rudra and Zoya time to get Goldman across the border to India. The Pakistani forces give Rudra and Zoya chase and only barely miss them before they bring Goldman over the border, where Ashwini is waiting. Once across, Goldman taunts them by saying how nothing has changed in India. Rudra shoots Goldman in the head, indicating that he is the face of the "New India."
D-Day is a well-researched, purposefully executed film. Much of the action takes places in 'actual' Karachi locations - the red light district of Napier Road, the busy thoroughfare of Empress Market and the environs of Qasim Port, among others.
