Agent Akash, also known as Sher Pathan, is recalled from leave to address a terrorist threat, only to discover his sister Roshni's urgent distress and subsequent murder, officially ruled a suicide. Believing it to be a cover-up, Akash uncovers a cryptic audio message and orchestrates his own incarceration to infiltrate a high-security prison, driven by a relentless quest for revenge and justice. Inside, he navigates a brutal environment of corrupt guards and violent inmates, forming a protective bond with an elderly inmate while becoming a target for the cunning Warden. An external party instructs Akash to identify and neutralize targets within the prison, hinting at a larger mission. Concurrently, medical professional Kavya repeatedly risks her life to hide fugitives and aid in escapes, eventually guiding Akash and his grandfather to safety, all while uncovering a conspiracy surrounding Doctor Roshni's death, which is linked to suspicious deaths within the prison. Akash's presumed death after an explosion is revealed to be a faked one, part of his intelligence gathering to plot vengeance against those responsible for Roshni's murder, including the corrupt Warden and influential Shankar/Shankara. Kavya herself is violently apprehended and interrogated, holding vital information about a dangerous individual. Akash, identified as Prisoner 412, makes an impossible entrance into the prison to rescue Kavya, who is held captive by Riya. Their desperate escape attempts are thwarted, leading to perilous confrontations. Shankara is revealed as the ruthless criminal mastermind behind an organ harvesting conspiracy and Doctor Roshini's murder, threatening Kavya with a similar fate. Driven by protective fury and a vow of retribution, Akash confronts Shankara, systematically dismantling his corporate empire with cunning twists and fabricated evidence. The narrative culminates in a high-stakes confrontation where a relentless Inspector exposes the Mastermind's organ trading racket, leading to a brutal firefight and the tragic death of a key agent, whose sacrifice is honored in the successful dismantling of the criminal enterprise.
