Bajirao Singham, who is now a DCP, gets transferred to Mumbai and discovers that one of his team members, Mahesh Jadhav, is found dead inside an ambulance with massive bags of money. Singham decides to unearth the truth behind it and in this process, he collides with a powerful and fraudulent religious leader, Satyaraj "Babaji" Chander, who has high-profile connections with corrupt politicians, including the ruling party's secretary minister Prakash Rao. During this period, Gurukant "Guruji" Acharya, the veteran leader of the ruling party who has been a teacher to Chief Minister Vikram Adhikari and Singham, is killed by Babaji's henchmen due to Guruji's opposition to Rao's scheme, even though Singham was present at the scene, making him vow vengeance. Because of this, he has to pretend that he has resigned in front of his family. Due to this, his father Manikrao asks him and his childhood friend, Avni Kamat, to come to their hometown, Shivgarh.
After some time, Singham and Avni fall in love with each other. However, it is then revealed that Singham hasn't resigned and came to Shivgarh on an undercover mission to find evidence against Babaji. At Wadhavpur, he catches Babaji's henchman named Altaf Khan who distributes the black money in order to bribe the voters. While coming to Mumbai with a convoy, it is attacked by Babaji's henchmen and Altaf is shot and slips into coma. On the other hand, Rao harms all of Guruji's candidates, including Avni, because her in-hiding brother Kishore is one of the candidates. Singham manages to save Avni and during a political event, the female family members of the candidates slap Rao due to this act. Altaf soon recovers and testifies against him. Singham arrests Babaji and Rao, leading to riots. However, some party workers execute an attack outside the court, killing the witnesses. This causes Babaji and Rao to go scot-free due to lack of evidence. Realizing the futility of the law, Singham and his team reach their house without wearing their police uniforms, joined in by police from all around Mumbai.
They successfully fight Babaji and Rao's men. Singham's team storm inside Babaji's house, and comically torture Babaji and Rao by firing a live round into both of their buttocks each. The wounded and humiliated Rao and Baba tell the truth, their confessions secretly being filmed and broadcast on live television and radio. A few weeks later, Guruji's party wins the elections. While being transported to jail in a van, Rao and Baba once again threaten and taunt Singham. Suddenly, the van stops and the driver walks away. A water tanker crashes into the van, sending it into a power station, killing both of them. One of Singham's allies, Inspector Dev Phadnis tells the media that there was a brake failure, and the incident is deemed as an accident (a plan that was fabricated by Singham which resembled the way Mahesh was killed).
