So the twins were torn asunder in the before-the-credits part of the film. Bunty strayed into
vilaayti (foreign) lands, while the twin’s father – Dwarka – strayed into Pakistan. The residual family in India – Parvati and Bittu - relocate to a new town. Parvati begins to work as a domestic help when a dizzy spell at work informs her employer of her pregnancy!
Parvati’s pleasure in the latest nishaani (momento) of her now-dead hubby is a bit mixed. She is happy but worries about making ends meet. Her kindly employers – Durga (Nadira) and Inspector Dev (Ifthekar) promise to take over the child, since they are childless, themselves. So, one fine day, Parvati and Durga go off to Kashmir, leaving Bittu behind with the other half of his to-be-sibling’s to-be-parents. Soon, Mom and Durga return with Durga’s baby daughter Shalu.
Before intermission, the vilaayti twin Shyam (Shashi Kapoor) was romancing Dhanno (Tanuja) and the desi twin Gopal (also Shashi Kapoor) had just left a drunk Kamini (Sharmila Tagore), to go to Kashmir to figure out why everybody was mysteriously interested in his maternal relative. I must warn you that this is a very looong post (with spoilers), since I’ve had compress the entire second half of the film in one post. For lack of space, I’ve had to concentrate on the main plot and neglect such delights as Helen trying to seduce Mr. Mehra (Shammi Kapoor), Dwarka (Pran, now Dilawar in Pakistani Intelligence) being smuggled into India, Shalu (Bindu) and her hubby Dheeraj (Ranjeet) sharing a cute romantic interlude in the police station where they’re both police officers, etc.
