Shiva (Akshay Kumar), a small-time thief in Mumbai, falls in love with Paro (Sonakshi Sinha), a girl from Patna, who is in Mumbai to attend a marriage. Shiva makes his way into Paro’s heart and she also starts loving him. Shiva tells her the truth about him being a thief and resolves to give up crime forever. But before that, he decides to swindle one last person for a large sum of money. This leads Shiva to Chinki, a young girl, who thinks that Shiva is her father. Flummoxed by what is happening, but forced to keep Chinki with her [as a police officer (Yashpal Sharma) keeps his eye on him], Shiva slowly starts loving the innocent child.

Although he tries keeping Chinki away from Paro’s eyes, the latter finds out about Chinki. Angry and hurt, Paro leaves for Patna. Shiva is heartbroken. Soon, unknown goons attack him, taking him to be a latter named Vikram Rathore, Chinki’s real father. While many unknown persons help Shiva run to safety with Chinki in his arms, he is soon surrounded by the goons. It is then that IPS Officer Vikram Rathore (also Akshay Kumar) makes an appearance and saves the day. But he is grievously injured in the fight.

It turns out that Vikram Rathore is Shiva's lookalike, and Shiva must fill into Rathore's position and finish off all the mafia goons, which leads him to a village named Devgarh
