Inspector Rakesh Kadam, an honest officer, is falsely accused of corruption by Jaikant Shikre, a powerful crime boss, politician, and businessman running illegal rackets in Goa. Unable to bear the disgrace, Kadam commits suicide. His widow, Megha, vows revenge, declaring that justice will prevail.
The story shifts to Shivgad, a village near the Goa-Maharashtra border, where Bajirao Singham, an upright Maratha police officer, commands the local police station. Respected for his informal yet effective problem-solving methods, Singham wins the villagers' admiration. His father Manikrao's childhood friend, industrialist Gautam Bhosle, visits Shivgad with his family, including his daughter Kavya. A series of comedic incidents lead to Kavya falling in love with Singham, admiring his integrity and simplicity.
Everything runs smooth until Jaikant, out on conditional bail for murder, is required to report to Shivgad every 2 weeks but sends a proxy. Enraged, Singham demands that Jaikant sign in person. Jaikant arrives with his army of goons and threatens Singham with his political and criminal connections, but backs off on being intimidated by the villagers, who warn to finish him off out of admiration for Singham after hearing his threats. Humiliated by Singham in front of the villagers, an egoistic Jaikant uses his political influence to transfer Singham to Goa, where he begins a campaign of harassment. In Goa, upon joining, Singham, through his colleagues Abbas, Phadnis and Savalkar, and Megha, discovers the extent of Jaikant's criminal empire, supported by corrupt officials like DSP Satyam Patkar, who is his senior, and Home minister Narvekar, while also learning of Kadam's suicide.
Being mentally tortured after several attempts to intimidate him are successful, Singham decides to move back to Shivgad. However, encouraged by Kavya, Singham gains motivation and starts dismantling Jaikant's operations by arresting his righthand man, Shiva, on trumped-up charges. Shiva's arrest reveals Jaikant's involvement in Kadam's downfall, along with other crimes like extortion, money laundering, and murder. Jaikant escalates the conflict by kidnapping Kavya's sister Anjali, but Singham rescues her and captures one of his minions, ultimately linking to Jaikant and Shiva. Jaikant's political party wins the election, and he becomes a minister, further complicating matters. Upon victory, Jaikant issues transfer orders for Singham, forcing him to leave Goa within 24 hours, while Shiva gives a statement protecting Jaikant.
At a police function the same night, Singham, arriving with Megha and Kadam's son, accuses his colleagues of betraying their duty by protecting Jaikant, and vows to finish him off single-handedly. Filled with guilt in front of their family members, the officers, including DGP Pawar, get motivated to join his fight. With the support of the entire Goa Police Force, including Patkar, who has a change of heart, Singham leads a raid on Jaikant's residence, who escapes after feigning an emotional monologue. Running throughout the city, Jaikant is captured after a dramatic chase and is shot dead by Singham in a staged encounter, seated in Kadam's chair, and Shiva is forced to change his statement at gunpoint. At a press conference, the team exposes Jaikant's crimes with Shiva's confession, clears Kadam's name, and restores Megha's dignity. The film concludes with Singham and his colleagues saluting Megha, symbolizing the triumph of justice and integrity.
