DCP Kabir Malik (Siddarth Malhotra) and his senior officer Joint CP Vikram Bakshi (Vivek Oberoi) goes on to investigate a series of bomb blasts in Delhi during the Delhi Police Raising Day. The serial blasts were committed by Zarar, an Indian Mujahideen (IM) terrorist, who is living under a fake identity as Haider with his wife Nafisa. Vikram and Kabir stop some of the six serial blasts and are asked to collaborate with Vikram’s classmate Tara Shetty (Shilpa Shetty), ATS Chief of Gujarat. They track down a suspect called Shadab, through sketches and witness accounts, and also learn about his hideout through an undercover officer.

Later, Kabir and Vikram decide to follow their lead without consulting Tara. However, their operation leads to an intense encounter between the agents and Zarar’s associates. Zarar takes a kid as a hostage after most of his associates are killed and Shadab is arrested, he shoots Vikram twice. Vikram succumbs to his injuries and dies. Kabir faces internal conflict with Tara and gets removed from the case. After a series of bombings in Jaipur, Kabir collaborates to investigate and his relentless pursuit leads him to suspect Zarar, who is in Goa and is planning major attacks with new accomplices and financial support.

Zarar and his team prepare for the bombings, but Kabir and Tara, following some leads, manage to thwart some attacks and arrest members of Zarar’s team. However, Zarar manages to escape again and Kabir tracks Zarar to Darbhanga. He reveals Zarar’s true identity to Nafisa, who is pregnant with Zarar’s child. Zarar leaves for Bangladesh and Kabir learns about his location through Nafisa. Kabir and Rana head for Bangladesh and meet up with Jagtap, Tara’s friend and a RAW agent.

Kabir, Rana and Jagtap ambush Zarar and his men at the station as Zarar was waiting for Nafisa to arrive. Zarar is taken to a military canp  before being transported back to Delhi. Tara reunites with the team, and with Kabir and Jagtap, they look forward to another mission to capture the IM’s leader and their team, including Rafeeq, who was recently spotted in Kathamandu.
