Sabse Bada Khiladi

Lallu travels to Bombay in search of work and secures a position as Jamna Das's loyal servant. He earns Jamna Das's trust through loyalty and discretion, shaping his early days in the household.

He finds Sunita drunk in a nightclub and brings her home, handling her with care and restraint rather than exploiting her vulnerability. Jamna Das notes Lallu's loyalty and decides that Lallu should marry Sunita.

Jamna Das dies suddenly of a heart attack, and his will demands Sunita marry Lallu to inherit the estate. Sunita initially refuses because she loves Amit, complicating the plan.

Sunita marries Lallu under the will's terms but promptly schemes to kill him with Amit's help so she can keep the wealth. Lallu remains outwardly loyal, unaware that his wife plans his demise.

They poison Lallu, place him in a car, and crash it to fake an accident. The death arouses suspicion, and Inspector Vijay Kumar, a lookalike of Lallu, is assigned to the case.

Vijay reveals that he has a twin brother Ajay who disappeared in childhood, reportedly murdered by Amar Singh, Amit's father. Amar had previously raped Gomti, Jamna Das's wife, and Gomti died after a court appearance when Amar pretended innocence; Sunita does not know these details, and Vijay vows revenge.

The twist unfolds when Lallu reappears before Sunita and Amit, alive and claiming to be Inspector Vijay Kumar. He discloses that he orchestrated the façade to frame Amit and his father, and that Sunita was part of the ruse. Amit and Sunita are arrested, and Kekda is also taken into custody for his role.

Amar Singh and Kekda hatch a plan to release Amit and smuggle him out of the country. They confront Vijay at the police station, trigger a fight, and Amit escapes to the airport after exchanging clothes with Kekda, who is immolated in the chaos.

Vijay manages to save Kekda and reveals that he is orchestrating the pursuit to nab Amit. The sequence cements Vijay's reputation as the master strategist, the 'Sabse Bada Khiladi'.

Vijay chases Amit to an abandoned airport, intensifying the pursuit through a burning hangar with derelict aircraft. In a risking helicopter confrontation, Amit shoots Kekda, but Vijay ultimately closes in on Amit.

In court, Vijay produces Amit and the fallen Kekda as evidence, exposing the conspiracy. Amar Singh publicly admits to killing Lallu and raping Gomti to protect his son, but destroys enough evidence to avoid conviction; he makes a last, failed attempt to shoot Vijay, after which both Amar and Amit are arrested.

With the conspirators arrested, the truth behind Lallu's death and Gomti's tragedy is laid bare. Vijay's ruse is exposed only to bring Amit to justice, and Sunita's schemes are undone as the law closes in on all involved.
