Lage Raho Munna Bhai

Munna rigs a contest to appear on Jahnvi's morning radio show for Gandhi Jayanti, pretending to be a college professor who specializes in Gandhism. He hopes to impress Jahnvi and win a platform to showcase Gandhi's principles. The deception centers on presenting himself as a true follower of truth and non-violence.

To prepare, Munna spends five days in a library reading about Gandhi's ideas. On the fifth day, he begins seeing and hearing Gandhi speak to him, convinced of the apparition's reality. Circuit remains by his side throughout.

Munna and Circuit visit a psychiatrist to check Munna's mental state, but Circuit blocks the doctor from revealing the truth. Munna remains convinced that Gandhi is real and continues to be guided by the hallucinated mentor. The doctor reluctantly treats him as mentally exhausted.

Munna delivers a lecture about Gandhi to the residents of the senior-citizens home, using his newfound persona. The talk is engaging, and Jahnvi is impressed by Munna's delivery and apparent sincerity. The audience receives the message with warmth.

Lucky Singh offers to fund a Goa trip for the Second Innings residents, aiming to influence the residents' minds. During the trip, Munna tries to propose to Jahnvi, but the couple discovers the trip was a ploy to take over the house. The episode exposes the underworld-backed scheme.

Khurana's plan to control Simran's engagement is driven by superstition and Batuk's numerology. Batuk suggests misfortune would arise if Simran marries, and Khurana accelerates the attempt to seize the Second Innings House. The extra 'k' in Khurana's name becomes a symbol of the manipulation.

Munna and Jahnvi co-host a radio program solving everyday problems through new takes on Gandhi's principles. They request listeners to send flowers to Lucky as a symbolic cure for his 'disease of dishonesty' in exchange for public, peaceful resistance. The show grows in popularity as a movement of Gandhigiri.

On Gandhi's insistence, Munna writes a letter to Jahnvi admitting the truth about his life. Heartbroken, she leaves Munna and quits the radio show. Munna's dream of winning her over seems to be dissolving as he clings to his beliefs.

Lucky stages a press conference to declare Munna mentally ill, with the support of Munna's psychiatrist who appears to back the claim. Public support shifts away from Munna, compounding his isolation. Yet Munna remains determined to carry on Gandhi's ideals.

Convinced Gandhi was only in his imagination, Munna plans to leave town but hosts one last radio segment to talk to Jahnvi. He ends up holding the studio hostage in a bid to reach her and salvage their relationship. The moment becomes a dramatic plea for truth and non-violence.

On her wedding day, Simran learns her father's deception and runs away to a taxi driver, Victor D'Souza, who had previously been helped by Munna. Victor connects Simran back to Munna so that the truth can come to light. The alliance's foundation begins to crack under pressure.

Munna convinces Simran to return and tell the truth; Khurana's plans fall apart as Munna and Circuit crash the wedding and confront Batuk about the deception behind Simran's engagement. Sunny decides to go ahead with the marriage anyway, despite the disruption. The confrontation marks a turning point toward resolution.

Munna and Circuit are arrested for causing a disturbance at the wedding, setting the stage for a final reckoning. At the police station, Jahnvi reconciles with Munna, and Lucky bails him out, returning the keys to Jahnvi's house. The two commit to pursuing Gandhigiri together.

Munna and Jahnvi marry and continue hosting their Gandhigiri radio show, spreading Gandhi-inspired solutions. Circuit finds a new home with a loving senior couple, while Victor achieves success and Simran and Sunny begin a family. Khurana reforms by firing Batuk and removing the extra 'k' from his name.

In the epilogue, Lucky sits in a library reading about Gandhi and begins to feel a change within himself. Gandhi appears to him, signaling a shared path toward truth and non-violence. The film closes with hope that Gandhigiri will continue through all who encounter him.
