In the mid-seventies, post the
Bangladesh Liberation War, Sultana Rahman fled to India after some attacks on her family. She stayed with Animesh Chatterjee, the then politician of the ruling party. Later, she returned to her country and became the Prime Minister of Bangladesh, while Animesh became the President of India. Back when Saahil Choudhury was studying MBBS in Thailand, he falls in love with Ayesha. He tops the class, but finds out that his mother was killed in a blast at a mosque. In a vulnerable condition, he is convinced to join JSM, the terrorist organization, and becomes the new face of Munir Alam. He becomes an expert in shooting
sniper rifles. Meanwhile, Ayesha realises about Saahil's terrorist connections and confronts him, to which he reacts violently and they get separated ever since. The Government of Bangladesh suspect some people who threat to overthrow their government. Meherunnisa Khan, the leader of the opposition party is meanwhile in a trip to India, who is suspected to influence the common people against the Government. In Burdwan, post the events of
Raktabeej, Gouri suspects everyone in the house, except Kanak. When her family doctor is out of station, he sends his student Ravi Shukla to take care of her, who is killed by Munir Alam (Ankush Hazra) and he becomes the imposter and infiltrates the family. Due to his caring nature, Gouri gains trust on him. Sanjukta enters a ladies hostel with her force, which is later revealed to be a den for storing arms for terrorists and illegal immigrants. However, one of the convicts are killed mysteriously just when Sanjukta raids the place. Pankaj returns to Bengal and once again joins hands with Sanjukta. They find out that JSM has activated their sleeper cell all over the
SAARC countries. As Animesh plans a visit to her in-laws' house in Bangladesh, he takes Gouri alongwith her. Munir convinces Gouri to join her wherever she goes in Bangladesh. One convict from the illegal immigrants case opens his mouth about mission M2, planned by the JSM and confirms that Munir is still alive. During a mission, Riya, a team member of Pankaj is mysteriously convinced to call Pankaj while she was travelling in police convoys, through which Munir confirms her presence in the exact convoy and shoots her with a sniper rifle from a far distance. Pankaj suspects foul play and immediately requests his superiors for a trip to Bangladesh, as the President's trip to Bangladesh was nearing. The JSM gets a tip of this information and plants Kalim, him being a namesake of Pankaj as a spy, whom Pankaj and Sanjukta mistakes to be planted by the Bangladesh Police, who were not co-operating with them from the very beginning and had confiscated their arms and mobile phones. Later when they catch the spy, before he reveals anything, he is again shot by someone mysteriously from a distance. The Bangladesh Police catch Pankaj, Sanjukta and their team with the dead man, and arrest them. Meanwhile, Munir kills a mechanic and infiltrates the Under 19 Cricket Tournament Opening Ceremony to be held in Bangladesh. Pankaj, Sanjukta and their team get bailed, but are not permitted to take any action. However on the day of the opening ceremony, Sultana and Meherunnisa are supposed to appear on stage together for the first time and unveil the World Cup trophy while Animesh is supposed to visit
Chittagong, at
Masterda Surya Sen's home to deliver a speech. Gouri, though willing to go with Animesh, changes her mind and visits the World Cup Tournament between India and Bangladesh on Munir's (Ravi) request. Pankaj realises that 'M2' refers to 'Minus 2' and that both Sultana and Meherunnisa are going to be targeted by Munir during the ceremony and they rush to the stadium. Before the ceremony, Ayesha, now a dancer, performs live on stage and anchors the ceremony. Bangladesh Police finally cooperates with Pankaj and Sanjukta. As the ceremony is about to happen, Munir shoots a bullet towards Sultana from a floodlight tower using his signature sniper rifle. Another mysterious bullet is fired at Meherunnisa, but both of them are saved as Pankaj intervenes and instead, the bullets slightly touch him and pass. After the entire stadium is evacuated, a thrilling showdown ensues between Pankaj and Munir, where Pankaj tries to convince Munir to quit terrorism but he jumps from the high floodlight tower and commits suicide. Ayesha, receiving this news and knowing Munir's true identity, reaches to the crime spot and gives her identity as his wife to the police, only to go visit Saahil's dead body. In a visual storytelling method, we see Munir's blood drops falling on the stairs of the gallery, which will eventually form another Munir. In the pre-credits scene, as Pankaj and Sanjukta finally establish a rapport between each other, Sanjukta casually kicks a vacant Coke can, which eventually blasts. As Pankaj falls apart against the car, it is revealed that the mysterious man killing the convict at the ladies hostel, misleading Riya as the driver of the convoy to call Pankaj to track her phone, killing Kalim on spot to frame the Indian officers, shooting the second bullet at Meherunnisa as a media cameraperson with the signature sniper and finally making the blast happen is none other than the new Munir, who continues to live on with the goal of Jihad. Apparently the protagonists fail to end the chain of terrorism and are still left to hunt down Munir, hinting at a possible sequel. == Cast ==
