Oh Darling! Yeh Hai India!

Don Quixote unveils a scheme to kidnap the president and replace him with a lookalike, then stage a public auction to force the sale of India. The plan is elaborate, aiming to create chaos and turn India into an asset for the don and his cronies. The overall goal is political and financial power, achieved through fear and manipulation.

Hero, a newcomer to Bombay and financially pressed, meets Miss India and the two connect with instant chemistry. They decide to spend the night entertaining each other, setting aside their troubles for a while. The meeting raises stakes as the larger plot looms in the background.

Meanwhile, Don Quixote's son Prince sets his eyes on Miss India, introducing a personal power struggle within the don's circle. His attraction adds a competing agenda to the unfolding intrigue and raises the danger for the heroes. The rivalry foreshadows political trouble for everyone involved.

The night turns dangerous as Hero learns Miss India's father is an abusive drunkard who wants her to enter prostitution, threatening her safety. In turn, Miss India discovers that Hero carries a brain tumor, adding a grave health risk to their budding romance. The couple's bond strengthens as they confront harsh truths.

Realizing the scope of Quixote's conspiracy, Hero and Miss India resolve to save the president and derail the auction. They begin to gather allies and information, preparing for a bold confrontation at the heart of the plot. The urgency of their mission supersedes personal conflicts.

Quixote is killed during rioting, and his son Prince seizes the throne, adopting his father's don persona to keep the criminal scheme alive. The shift widens the danger as the new leadership resumes the plan with renewed energy. The political landscape becomes more volatile than before.

Disguised and determined, Hero and Miss India infiltrate the auditorium where the auction is to take place. They move with care, intent on exposing the conspiracy and protecting the president, all while keeping their cover intact. The stakes are high as the operation inches toward execution.

Prince, wearing his father’s don attire, arrives with a cadre of henchmen to oversee the auction and confront the intruders. His presence signals that the confrontation will be violent and decisive. The crowd is unaware of the deadly game unfolding around them.

Hero, Miss India, and their friends launch a bold counterattack, overpowering Prince's cronies and turning the tide of the confrontation. The operation brings several allies into play and exposes the fake leadership behind the auction. Chaos erupts as plans unravel in real time.

People rescued earlier from danger execute their plan to kill the fake president by forcing a hose into his mouth, inflating his stomach until he explodes. The gruesome demise eliminates the symbol of the conspiracy and shocks the onlookers. The act marks a major turning point in the battle for control.

Prince attacks Hero and Miss India, triggering a violent scuffle that sends them through shattered glass. They improvise a parachute from an Indian flag to escape the collapsing structure. The escape demonstrates their ingenuity and resolve in the face of danger.

Hero and Miss India land on the roof of a double-decker bus after their escape, with Hero declaring that he is glad to be alive. Miss India reminds him of his brain tumor, and he reveals the X-ray they saw was from a year and a half earlier, reframing the stakes for their future. Their bond survives the ordeal and the danger dissipates as they move forward.
