Akshay Kumar plays the titular character, Jagdishwar Mishra, replacing the 2013 film's lead actor, Arshad Warsi, while Huma Qureshi, Annu Kapoor and Kumud Mishra, as well as Saurabh Shukla, who reprises his role from the 2013 original, star.

Based in Lucknow, the story follows a lawyer who fights a case against a ruthless and powerful advocate to bring justice to the deceased victim of a fake encounter involving a corrupt police officer and a terrorist presumed dead.

Jagdishwar "Jolly" Mishra (Akshay Kumar) is a Lucknow-based lawyer who stays with his wife Pushpa Pandey (Huma Qureshi) and son.

Seeking to arrange money for his own chamber, Jolly lies to a widow, Hina Qasim, telling her that Mr. Rizvi will take her case and that the fee is 200,000 rupees.

Singh then hires Lucknow's best lawyer, Pramod Mathur (Annu Kapoor), to fight his case.

Jolly is able to get a copy of the FIR and other papers regarding the case with the help of a bookie, Guru Ji, in Varanasi by paying him a sum of ₹500,000 by selling his own chamber.

However, even though Justice Tripathi orders disciplinary action against Jolly for showing allegedly dishonest evidence, the Chairman of the Disciplinary Committee, who turns out to be Mr. Rizvi himself, gives Jolly four days of time to prove his worth, as he feels guilty for not fighting the case in good stead.

Jolly and Pushpa, while analyzing Hina and Iqbal Qasim's wedding album, notice an unknown cop from Kashmir called Fahim Bhat.

Jolly travels to Kashmir and gets confirmation of the truth from Fahim, who visited Lucknow to identify the terrorist during Iqbal Qasim and Hina's wedding.

Fahim, now suspended and arrested in a fake case, reveals that Qasim, who died in the encounter, was not the real terrorist and that he also filed a complaint against Singh.

Mathur tries his best to avoid Fahim from giving a statement in the court as he stops the proceedings in the courtroom by sitting on the floor in protest.

After initial reluctance from Justice Tripathi, Jolly rapidly fires questions to Iqbal by asking him details of the Shastras.

Justice Tripathi then declares Qasim innocent and orders Quadri's arrest, giving life imprisonment to Singh along with his accomplices on charges of murder, erasing evidence, misleading the court, and showing false evidence as Jolly wins the case.

The firm Kochhar & Co, on behalf of Bata India, had issued a legal notice to the filmmakers for the comment and filed a lawsuit of ₹30 million (US$340,000).
