"The film starts with ACP Yashvardhan (John Abraham) in the hospital, recalling the accident that changed his life forever. Yash is a dutiful, responsible and stone-hearted police officer whose only passion in life is crime-fighting. He has no family or loved ones and has been alone in life since he can remember. Everything changes when Yash meets Maya (Genelia D'Souza), an independent and lovely woman. Though the two get off to a rocky start, Maya warms up to him once she realizes he is a police officer, and apologizes for the misunderstandings they had. When Maya gets hit by a car in front of Yash, he rushes her to the hospital. With that, the two bond and start to meet and go out regularly. Maya confesses her love to Yash, but Yash refutes her advances, as he does not want her to become his weakness in his professional life. However, Swati (Sandhya Mridul), the wife of Yash's coworker and friend, convinces Yash that he is in love with Maya as well and Yash decides to get married to her.
In the big drug case the unit is investigating, Yash, along with his co-mates, Mahesh Pande(Raj Babbar), Atul Kalseka (Mohnish Bahl) and Kamlesh, kill Reddy (Mukesh Rishi) while he is peddling drugs. Yash, Mahesh & Kamlesh are suspended for killing Reddy instead of arresting him. Reddy's heartless and aggressive brother Vishnu (Vidyut Jamwal) vows to avenge his brother's death by killing all of the officers, including Yash. Yash and the other officers prepare themselves for Vishnu, but Vishnu successfully intrudes into Mahesh's home and brutally murders him after raping his wife Rachana (Anaitha Nair). The event leaves Yash and the other officers shaken but Yash and Maya's marriage take place. Meanwhile, Vishnu decides to attack each of the officers' weaknesses; he kidnaps Swati, Atul's wife, and Atul is forced to tell him where Yash will be that night. Yash and Maya passionately enjoy their wedding night of love and bliss; however, this proves to be their first and last night together, as Vishnu and his henchmen invade the house and attack Yash and Maya the next morning.
Yash is fatally shot and Maya is kidnapped in the attack. Yash miraculously survives the attack. Vishnu tells Atul that he will release Swati if Atul kills Yash. However, Atul cannot bring himself to kill his friend and instead joins forces with Yash to execute a plan against Vishnu and save Maya and Swati. Yash, Atul and Kamlesh all go together to the place where Vishnu has been keeping Maya and Swati hostage and find, in horror, that Swati has already been murdered. In despair and heartbreak, Atul kills himself after seeing Swati's body. Out of the 4 police officers, only two are left now: Yash & Kamlesh. Yash and Kamlesh go together and face Vishnu in a final confrontation. Kamlash is shot but survives. Vishnu shoots Maya in front of Yash and drops her from the second floor. Yash catches her but is unable to save her. Maya assures Yash that she has gotten her wish of being with him and dies
