Shahenshah is a 1988 Indian Hindi-language vigilante action film starring Amitabh Bachchan in the title role, along with Meenakshi Sheshadri. The film was produced and directed by Tinnu Anand. The story of the film was written by Amitabh Bachchan's wife Jaya Bachchan and the screenplay was written by veteran screenwriter Inder Raj Anand.
Plot: A corrupt and sniveling bank manager Mathur (Prem Chopra) has illegally borrowed 2.5 million rupees and loaned them to crime baron J.K. Verma (Amrish Puri). J.K orchestrates a bank robbery to bail him out. Inspector Anand Shrivastav (Kader Khan) gets wind of this plot. He is about to crack the case when J.K. enlists an exotic dancer, Julie (Aruna Irani), to use the robbery as a backdrop and frame the honest inspector for corruption. Inspector Shrivastav is arrested by the CBI and is imprisoned for three months. Inspector Shrivastav, the honest and innocent inspector, is so depressed about the false charges that he hangs himself at home after being released on bail. This creates a lasting and powerful impression on his young eight-year-old son, Vijaykumar. Vijay retains the noose his father used to hang himself. He vows someday restore his father's honour. Vijay and his mother leave their house and live in the house of another honest police inspector named Aslam Khan.
Years later, a young Vijay (Amitabh Bachchan) in the inspector uniform, grows up in the care of Inspector Aslam Khan (Pran), Inspector Shrivastav's friend and partner, who has allowed Vijay and his mother to live with him, and Vijay becomes a cop himself. Vijay is friends with Shaheena, the daughter of Aslam Khan. Aslam Khan is an honest cop much like Vijay's father. Vijay is an obsequious and cowardly inspector, prone to bribery and generally scared of powerful criminals. It doesn't take JK long to find Vijay, get him on the payroll, and run his underworld crime empire (drugs, guns, racketeering) past the cops.
A new apparition bursts upon this scene who calls himself "Shahenshah", a costumed crime fighter (see movie poster). He has a left iron hand which is used to attack enemies and smash objects, and Shahenshah's other weapon is a noose. Oddly enough, it is the same noose Vijay's father used to hang himself with. This is because it is revealed later that Shahenshah is actually Vijay. When wearing Shahenshah's attire, Vijay describes himself as "one who doesn't hold a cop's job but does the same work; one who apprehends criminals himself, conducts the trials himself, and, pronounces and executes the sentences himself". So Vijay/Shahenshah's outward mission is to take out crime, but his real goal is to get to the guys who framed his father.
Shahenshah quietly breaks up several of J.K.'s gambling dens and illicit liquor distilleries. He also halts the demolition of a slum. This catches the eye of small-time trickster Shalu (Meenakshi Seshadri) who lives there with her aging and ailing mother Julie. J.K. had ordered her assassination after she helped frame Vijay's father; she has been on the run from him ever since, which becomes Shalu's motivation for seeking out and eliminating J.K. Shalu decides to infiltrate J.K.'s coterie by becoming an exotic dancer. One night, she attempts to kill J.K. by shooting him but is shocked when J.K. reveals he had been wearing a bullet-proof vest the whole time. Vijay lies to J.K. that Shahenshah's weakness is not letting Shalu die. He also lies that if J.K. returns Shalu to Shahenshah, Shahenshah will return J. K.'s goods worth millions. But J.K. is ultimately fooled. Shahenshah later detonates a bomb planted in J.K.'s truck.
J.K. murders an honest crime reporter Mohammed Salim (Vijayendra Ghatge), who was about to expose J.K.'s crime ring. Salim was married to Shaheena (Supriya Pathak), the daughter of Aslam Khan. Vijay now decides to turn around his image as a cowardly cop. He openly defies J.K. Julie agrees to testify against J.K. Shalu provides ancillary evidence. And J.K. prepares for an all out war against Shahenshah/Vijay, Shalu and the lot of his enemies. At Salim's funeral, only one of the many witnesses of his death were present. He was about to reveal J.K.'s name, but a sharpshooter shoots him to death.
There is a veritable bloodbath on the streets as Inspector Vijay tries to get Julie into the courthouse. And there is a final showdown where Shahenshah reveals his secret identity and becomes the nemesis for all the culprits. To give himself a chance to escape, J.K. abducts Shalu. The showdown leads Shahenshah chasing J.K. to the roof of the courthouse where J.K. is pleading his case, because his cover is blown. J.K. falls through a hole in the roof and is clinging on for dear life, with the whole court looking in astonishment. Shahenshah then reveals before the whole court that he is actually Vijay. Vijay throws the noose down to J.K., and he gratefully accepts it, but J.K., being the ruthless man that he is, attempts to attack Vijay. Vijay lets go of the noose, which slips around J.K.'s neck, and before the whole court, J.K. Verma is hanged, avenging Inspector Shrivastav and Salim the reporter, Shaheena's husband.
