The video goes viral, and so does Bhavna's tweet supporting Karan. A fight breaks out, resulting in Karan getting thrown out of the house by an explosion. Karan and the team arrive at the home, but outside it is stopped by Buraq's goons. Karan retrieves his phone and answers Buraq's call, further telling him he would soon visit the dead suspect's house. While pursuing a suspect, Karan meets Zahira and Abeer and soon gets involved in a bike chase with the suspect, resulting in the latter's accidental death. Learning two Indian agents have arrived in London to capture him, Buraq enlists his agents' help to track them while Karan and his team go through the same process to follow Buraq's agents. Abeer's mother and Buraq's ex-wife Zahira ( Feryna Wazheir) wants to contact the police but is threatened by Buraq. On the other hand, the British terrorist Buraq Ansari ( Gulshan Devaiah) forces his son Abeer ( Atharva Vishwakarma) to watch him kill a man. Posing as a married couple, they arrive in London where Mallika Sood ( Angira Dhar), a British Intelligence officer, picks them up and takes them to their work station where another agent named Armaan Akhtar ( Sumeet Thakur) assists them. Further learning the recordings were shot by a camera in London, Karan decides to go undercover along with Bhavna Reddy ( Adah Sharma), who assisted him on his previous mission. Also, one of the suspects talks repeatedly about 9/11, which is decoded as an attack on India on the day of Diwali. Upon investigating further, Karan learns the suspects received money and VHS tapes containing a terrorist's message. Karanveer 'Karan' Singh Dogra ( Vidyut Jammwal) is called to help the police, but one of the suspects kills himself. The Mumbai Police officers arrest three young terror suspects and try to interrogate them but get no information.
