Veera Raghavan, an Indian RAW field agent is assigned to capture a terrorist named Umar Farooq. While he successfully manages to do so, a missile shot by him to prevent Farooq's escape injures and kills a civilian child, traumatising Veera, who quits the agency and returns to Chennai. 11 months later, Veera is still relieving from post-traumatic stress disorder (PTSD). He meets Preethi at a wedding, and they fall for each other, where she convinces him to join her company Dominic & Soldiers, a failing security service. Meanwhile, the Tamil Nadu government gets intel that a major terrorist event is planned in Chennai.Along with Preethi and her boss Dominic Irudhayaraj, Veera visits the East Coast mall, which is their last client where he observes a series of suspicious activities and deduces that someone else has taken over the mall. Veera is proven right, as terrorists, led by Umar Farooq's brother Umar Saif, open fire and hijack the mall. Veera, Preethi, Dominic and others hide unharmed inside an unopened restaurant. The government, led by Deputy National Security Advisor Althaf Hussain, tries to negotiate with the terrorists, who demands the release of Farooq. Althaf learns that Veera is also trapped inside the mall and manages to establish contact with him, where he tries to convince Veera to help them.Though initially hesitant, Veera gets convinced when he realises that the terrorists are here for Farooq, where he kills one of the terrorists and captures another one alive and brings him to their hideout. Veera manages to infiltrate the terrorists and eliminates a few of them. The Home Minister, who is in league with Saif, gets them to stage the execution of his wife and daughter Aparna, who are also in the mall on live television. The government succumbs to this and agrees to release Farooq. Enraged, Veera retaliates and kidnaps the Home Minister's wife and Aparna where he pretends to be a Bangladeshi militant to confuse the terrorists, and threatens to kill them if Farooq is released.Senses his impending defeat, Saif seemingly gives up, only to slip among the crowd pretending to be a hostage, and soon figures out Veera's real identity due to Dominic where he forces him and his aides to give up and captures all of them. With the help of Aparna, Veera manages to escape, and eliminates Saif and the other terrorists while making sure that the hostages escape to safety. The Home Minister is arrested for his involvement in the hijack. Despite all the negotiations, Farooq is released. Few months later, Veera captures Farooq in Pakistan and after surviving a long air chase, manages to bring him back to India to have him imprisoned. After the mission, Veera, Preethi, Dominic and the rest of his crew celebrate their escapades in Goa.
