He is suspected of the murder and is interrogated by the intelligence head Arun Joshi, who later allows him to walk free. Upon noticing a man clicking pictures during the cremation of Sadiq, Kabir chases him and instead ends up meeting with analyst Isha Khanna. Decoding a message left by Sadiq before his death, Kabir comes to the conclusion that this mission in Balochistan would be unsanctioned, and would involve him, Isha and another agent named Veere Singh who has been working undercover for a long time and wants to go home. Teaming up to complete the mission once they meet, Kabir and team face a lot of challenges on their way to Quetta while Arun learns of the unsanctioned mission and starts tracking them.
