The opening scenes show a rape victim's father Veerendra Saxena approaching Sarkar for justice which the corrupt law and order system has failed to deliver which Sarkar promptly establishes by having the rapist beaten up by his henchmen. Sarkar's other, more upright son, Shankar Abhishek Bachchan , returns from the United States with his love Pooja Katrina Kaif after completing his education there. Pooja's doubts about Sarkar's image cause Shankar, who firmly believes in his father's righteousness, to break up with her later in the movie.
One day, a Dubai -based don, Rasheed Zakir Hussain tries to strike a deal with Sarkar; he promptly refuses on moral grounds and also forbids him from doing it himself. Meanwhile, they trap Sarkar by assassinating a righteous, upright, Ahimsa political leader and an outspoken critic of Sarkar, Motilal Khurana Anupam Kher , and frame Sarkar for the murder. Everyone, including Vishnu believe that Sarkar is guilty but Shankar has deep faith in his father.
Sarkar gets arrested and is imprisoned. Shankar now takes over the position of Sarkar temporarily. On learning of a plot to murder his father in prison, he approaches the police commissioner Anant Jog and asks him to arrange stronger security for his father, only for the commissioner to mock Shankar and his father besides not providing protection. Shankar gets a feeling that the police commissioner wants Sarkar to get murdered. Shankar and Khansaab, one of Sarkar's men, try to ask Selvar Mani for help to prevent possible murder, but Mani ultimately betrays them when he reveals that he is in an alliance with Rasheed.
Rasheed prepares to kill Shankar and Khansaab but only Khansaab is killed when he decides to sacrifice himself for Shankar.
By the time Shankar reaches the prison and appropriate action is taken, the attempt on Sarkar's life is already made. Sarkar is later acquitted. He remains bedridden as Shankar takes on Sarkar's enemies. Vishnu was previously thrown out of Sarkar's house because he had murdered the actor who was having an affair with Sapna. Vishnu returns home pretending to have repented. Shankar eliminates Rasheed, Vishram and Selvar Mani.
He also succeeds in making Swami his puppet. This results in legal action against the Chief Minister. The closing scenes shows a woman approaching Shankar for justice to a fake encounter of her husband by the police and calling Shankar the Sarkar, while Subash is busy with family.
