Amar Manohar and Prem Bhopali are daydreamers living with their fathers Murli and Bankelal. They learn that Ram Gopal Bajaj's daughter Raveena is returning from London to India, and they decide to woo her to gain a share of her father's wealth. Their motive is practical and comic, driving the early schemes of the film.

Amar and Prem escape their towns and board a bus bound for Ooty where Raveena and Karishma live. They quickly realise they share the same goal and compete to win the women’s affection. Against the odds they manage to enter Raveena and Karishma's house in Ooty, starting the masquerade.

Inside the house, Amar pretends to have lost his memory and eyesight after being knocked out by Raveena, while Prem pretends to be a doctor to cure him. In the mêlée, Prem also falls for Karishma, the secretary, complicating their plans and setting up comic tension.

Ram Gopal Bajaj has an evil twin, Teja Bajaj, who plans to kidnap him and impersonate him in London. Teja sends his henchmen Robert and Bhalla to live in Raveena and Karishma's house as servants, quietly orchestrating the larger kidnapping plot.

Amar and Prem realise that Karishma the secretary is actually the wealthy Raveena, while Raveena is the secretary Karishma. The two lovers adjust to the new truth and the swapped identities complicate their affection for the real people.

Ram Gopal Bajaj arrives in India and immediately sees through Amar and Prem. He refuses to consent to marriages, prompting the duo to plan a fake kidnapping to stage a hero rescue and win his approval.

Robert and Bhalla successfully kidnap Ram Gopal, leaving Amar and Prem shocked by the sudden turn of events. Teja's scheme now begins to take shape as the real prize—the diamonds—faces serious risk.

Amar and Prem head to Teja's hideout to rescue Ram Gopal, but they mistake Teja for Ram Gopal and abduct Teja, bringing him to his own house. The chaotic move fuels comic misunderstandings and shifts the balance of power.

The next day, Raveena and Karishma share their suspicions with Amar and Prem. They secretly follow Teja to his hideout, where Ram Gopal tricks Teja and makes him escape. Amar and Prem nevertheless imprison Ram Gopal again, mistaking him for Teja.

The escapee Teja slips away while Amar and Prem are trapped; Teja uses this to widen the chaos. Meanwhile, Amar and Prem manage to convince Robert and Bhalla that Ram Gopal is Teja and they free him from prison.

Amar, Prem, Ram Gopal, Robert and Bhalla converge on Gogo's hideout as Crime Master Gogo is drawn into the mix by Teja. The police, alerted earlier, arrive and arrest all of the criminals in a comic yet decisive standoff.

Ram Gopal finally recovers all of his diamonds and agrees to the marriages with the real Karishma and Raveena, completing the tangled set of romances that began the plot. Amar and Prem win the true loves despite the many disguises.

With all villains arrested and the lovers united, the film ends on a light note as the couples prepare for the weddings. The mistaken identities are resolved and the wealth motive has been discarded in favor of genuine affection.
