She is now of marriageable age, and her businessman father, Sardar Roop Singh wants her to marry his friend's son, Sohan, but Nisha dislikes him.

While traveling to Darjeeling with a dance troupe, she meets Popat Lal, the son of one of her father's business associates, and after a few misadventures, both fall in love with each other.

The famous song "Aaj Kal Tere Mere Pyar Ke Charche" (used in Brahmachari (1968)) was written for this movie but was not included as Dev Anand rejected it.

[citation needed] Many of the songs went on to become classics and are still popular today, particularly, "Jiya O Jiya (Jab Pyar Kisi Se Hota Hai)" and "Teri Zulfon Se Judai," sung by Mohammed Rafi, were big hits, as was "Sau Saal Pehle," sung by Mohammad Rafi and Lata Mangeshkar.
