Ranvijay “Vijay” Singh is the son of Balbir Singh, a Delhi-based business magnate who heads the generational steel company, “Swastik Steels”. Vijay’s family includes his father, mother Jyoti, and sisters Reet and Roop. Vijay has adored Balbir since childhood, but Balbir neglects him and is harsh with him due to his busy schedule. After an incident where a teenage Vijay brings an AK-47 to school and hurts a group of boys who bullied his sister, Balbir sends him away to a boarding school in United States.
Vijay returns to Delhi after completing his education, where he attends the engagement of his former school classmate, Geetanjali “Geeta”, whom he has always loved. He convinces her to break her engagement and choose him. During Balbir’s 60th birthday, Vijay fights with Reet’s husband, Varun, and is kicked out of the house. He marries Geeta and moves to the United States, and they have two kids. Eight years later, after no contact with his family, he learns that his father was shot. He promptly returns to India and sets out to find the person responsible for the assassination attempt.
Vijay goes to his native village in Punjab, where he rounds up his cousins to help in his mission. He sets up a doppelgänger for Balbir who is killed by Asrar Haque’s men. Vijay then discovers that Varun was involved in the assassination attempt, after which, he kills him at a meeting as Asrar Haque watches the murder. Shortly afterward, Vijay goes to meet an arms dealer, Freddy, at a hotel, where Asrar Haque and his assailants, donning animal masks, arrive at the hotel to kill him.
However, Vijay manages to vanquish them despite brutal injuries and goes into a coma. Two weeks later upon waking from his coma, Vijay learns that he has heart failure and needs an immediate transplant. Vijay finally finds a donor and successfully recovers. He learns that the donor is the fiancé of a woman named Zoya. Vijay meets and begins to spend time with her to ease her pain of losing her fiancé, which leads to an affair. Zoya, who has fallen in love with Vijay, reveals that the donor was not her fiancé and reveals that she was sent by Asrar’s mute younger brother, Abrar, to honey trap him. Vijay learns that Asrar was the actual perpetrator behind Balbir’s assassination attempt.
Asrar’s younger brothers, Abid and Abrar, discovered everything about Vijay and sent her to him. Vijay reveals that he had known earlier that she had been sent by someone and that he wanted to know the identity of the actual perpetrator. Later, he learns from his grandfather, Rajdheer Singh, that Abrar and his brothers are related to their family, due to them being the grandsons of his late younger brother, Shamsher Singh, whom Rajdheer had banished from the family years ago due to the latter’s involvement in shady dealings during his time with “Swastik Steels”, thus making Vijay their cousin. Asrar tried to assassinate Balbir after his father, Azim Haque, was denied a share of their property. Shamsher committed suicide soon afterward, an incident that Abrar had witnessed as a child and left him heavily traumatized, rendering him mute.
Vijay learns that Abrar has relocated to Scotland and converted to Islam, plotting revenge. Vijay and his cousins barge into his house to kill him. He kills Abrar’s men and threatens Abrar’s wives to reveal his whereabouts. Abrar’s wives reveal that Abrar had escaped with Abid and plans to leave for another country in their private jet. Vijay and his men give chase to them on the runway, managing to stop their flight. A brutal fight ensues, where Vijay finally kills Abrar and returns to India. During their Diwali celebration, Balbir reveals to Vijay that he has terminal cancer and realizes that his upbringing is the reason behind Vijay’s aggression. Balbir finally apologizes and reconciles with Vijay, who is overjoyed after finally receiving familial love and affection from his father.
In the post-credits scene, Asrar, Abid, and Abrar’s other younger brother, Aziz, a professional assassin in Istanbul, learns that Vijay is responsible for killing Asrar and Abrar. After successfully undergoing plastic surgery to become Vijay’s doppelgänger, Aziz and Abid set out to exact vengeance on Vijay and his family.
