12 years later, while traveling in a flight, Arjun meets an air hostess named Ayesha (Jacqueline Fernandez) and they fall in love. When both of them are about to take their relationship further, a terrorist attack occurs at the airport and Ayesha is killed, leaving Arjun badly injured. Arjun is wheel-chair bound, with movement only in his neck. Through the news, he finds out that the attacker of the airport was Hamid Gul (Elham Ehsas), the son of Rehman Gul and the suicide bomber he saved 12 years back. He realises that the attack on the airport was arranged by Hamid Gul to take revenge for his father because the Indian Army captured his father. The Indian Intelligence Chief, V. K. Subramaniam (Prakash Raj), comes up with the idea of introducing supersoldiers, operated by robotic and artificial means, in the Indian Army to save lives in times of war. These supersoldiers will be designed by Dr. Sabaha Qureshi (Rakul Preet Singh). Subramaniam chooses Arjun for this mission as a trial participant. While going through the surgical process, Arjun's chances of survival are shown to be minimal, but he manages to survive the on-boarding process and successfully turns into a supersoldier. He operates under the command of the Intelligence Robotic Assistant (IRA) chip, designed and implanted by Sabaha.
