The police get information that 10 tehsildars across Maharashtra have been mysteriously kidnapped. But they are mysteriously returned – except the most corrupt officer, who is hanged in public. The police get a CD from mystery man ‘Gabbar’ who says his mission is to target corrupt officers. Police driver Sadhuram (Sunil Grover) is convinced that he can crack the mystery of who is Gabbar – but his superior officers humiliate and insult him in front of all the other officers.
On his way home, Professor Aditya Singh Rajput (Akshay Kumar) is stopped by lawyer Shruti (Shruti Haasan), who makes him drive her and a pregnant woman to the hospital, but the woman delivers in the car with Shruti’s help. When Shruti wants to thank Aditya for helping her, she finds he has already left. Sadhuram finds from the tehsil to the district offices that there’s one honest officer in each department. He is convinced that all these honest officers have a link to Gabbar. Shruti and Aditya become close and one day, she gets hit by a scooter and Aditya takes her to Patil Hospital. Although not badly injured, doctors at Patil Hospital insist on taking expensive tests and Aditya realizes how helpless patients and their families are fleeced and often, inhumanly treated. A poor woman mourns her deceased husband in the civil hospital nearby. Aditya tells her he’ll get her medical insurance. He deliberately checks in her dead husband as a patient to Patil Hospital. The hospital tries to swindle money out of Aditya by pretending to treat the already dead man, making Aditya pay heavily for tests and medicines. Aditya then shows them the death certificate, which proves that they knowingly admitted a dead man. The young owner of the hospital, Vikas Patil is furious when Aditya releases the video of the hospital’s corruption to the media. However, Vikas is brutally and mercilessly murdered by an angry mob. His father, a powerful builder Digvijay Patil (Suman Talwar), sees Aditya in the hospital CCTV footage and is stunned to realize that this is the same man he had supposedly killed five years ago.
