On March 9, 1993, a low-level thug named Gul Mohammed finds himself behind bars at the Nav Pada police station, where he endures severe beatings. In a desperate bid to save himself, he confesses to a conspiracy targeting crucial sites around Mumbai, revealing that Tiger Menon is at the helm of a harrowing plot to orchestrate bombings at major locations such as the stock market, government offices, and train stations. Despite Gul's alarming claims, the police choose to disregard his confession.
Fast forward to March 12, a day marked by tragedy as Bombay is ripped apart by a series of catastrophic explosions, leaving over 300 dead and around 1,600 injured. Amidst the chaos, investigators like Inspector Sawant (Ravi Kale) and Inspector Nandakumar Chaugule (Zakir Hussain) strive to unravel the tangled web of deception surrounding the bombings. Their pursuit leads them to find RDX explosives smuggled into the city, complicit customs officials, and a weapons-laden van that holds a passport belonging to Rubina Memon, uncovering ties to Tiger Menon.
In a significant turn of events, Tiger, while in Dubai, acknowledges his involvement in the bombings. However, he faces challenges, as authorities are now aware of his connections due to the van. Back in Bombay, the police uncover an unexploded RDX bomb concealed within a scooter, which leads to the identification of associates connected to Tiger, including his sister Rubina, who becomes a focal point in the investigation.
Arrested on March 14, Asgar Muqadam (Nawazuddin Siddiqui), Tiger's secretary, spills vital information under duress, implicating numerous co-conspirators such as Ayub Memon and Yakub Memon. The investigation tightens as it is revealed that the entire Memon family had fled to Dubai just before the bombings transpired.
As chaos reigns, Deputy Commissioner of Police Rakesh Maria (Kay Kay Menon) takes charge of the case. The aftermath of the bombings wreaks havoc on the lives of the accomplices, who must now live in secrecy, their passports mysteriously destroyed under Tiger's orders. The mounting pressure of police investigations leads to the arrest of key figures like Badshah Khan ([Aditya Shrivastava]) and others, who become pawns in a grim game of cat and mouse.
In a desperate bid for survival, Badshah Khan, who had gone underground, learns the harsh truth: tiger's plans for their escape were merely illusions. Frustrated and abandoned, he ultimately chooses to turn against Tiger and cooperate with the police, revealing the gruesome truth behind the bombings — a response to the violent communal clashes of late 1992.
Within this violent backdrop, Tiger Memon ([Pavan Malhotra]) emerges as a notorious underworld figure whose initial motives for retaliation ignite the events of Black Friday, March 12, 1993. The investigation expands further, leading to the Central Bureau of Investigation's involvement, as they delve deeper into the scandal involving Dawood Phanse ([Gajraj Rao]) and others, portraying a chilling tableau of crime and chaos.
On November 4, 1993, the police finalize their charges against 189 individuals connected to the blast, a move that foreshadows a lengthy pursuit of justice. Ultimately, on August 5, 1994, in a surprising twist, Yakub Memon turns himself in, shedding light on Tiger's integral role in orchestrating the deadly conspiracy that forever altered the landscape of Bombay.
