Synopsis: While returning from Army Base, Captain Ajit Kapoor stops over at a rest-house, where there is a party on, and he meets a charming, vivacious young lady. When he reaches home, his guardian, Father Joseph, wants him to get married. When Joseph accompanies Ajit to see the girl, whose name is Kanchan, Ajit is thrilled to find out that it is the very same girl he met at the rest-house. Ajit indicates his approval, and the stage is set for them to get married. It is then Ajit finds out that the Kanchan is not the girl is he had met, but her twin-sister. Kanchan is heart-broken at this, but wants her sister to be happy. Ajit is even more happy when he finally meets Kamini, who also recognizes him. Then Ajit's Army Colonel summons him for assistance in locating a female spy, who closely resembles the twin sisters'.
Captain Ajit (Shashi Kapoor), stationed in Kashmir, is instantly smitten when he meets the spunky, aggressive Kamini (Rakhee). Kamini disappears after one dazzling evening of poetry, though, and Ajit despairs of ever seeing her again. Then Ajit's adoptive father, the kind-hearted Father Joseph (Nazir Hussein), unaware that Ajit has fallen for Kamini, seeks to arrange Ajit's marriage to Kamini's excruciatingly bashful twin sister, Kanchan (Rakhee, the other half of her dual role). Ajit is briefly confused, but all seems set straight soon enough, and Ajit is set to marry his sprightly Kamini; Kanchan is depressed but resigned to her wallflower status. When a shady gunda from Kamini's past surfaces, however, things take a turn for the weird, and a whirlwind of mistake, confusion, and deception follows, with an aerial climax worthy of the most over-the-top masala imaginable. Kamini, brash and modern, attracts all the attention; suitors come to the family to consider marriage to the modest, retiring Kanchan and end up enchanted with the flashy, outspoken Kamini. She even wins the heart of Ajit, the ideal Indian man, a loyal and heroic soldier, obedient and deferential to his elders. But the film punishes Kamini, and in the end it is the traditional Kanchan who is exalted and glorified
