Her wealthy father, worried by her distraction consults a psychiatrist who pronounces that Sapna needs treatment and must be sent to his clinic for an extended period of time.
Running away from home, in a beautiful red MG TF (probably a 1954 model) she comes across Sunil (Shashi Kapoor) working on his Jeep (one of the early right-hand drive versions that Mahindras produced).
A couple of accidents later they find themselves in a luxurious Mercedes Benz tour coach (possibly an O 321 H - with a rear engine) and their journey of exploration begins.
Faced with obstacles, raised by greedy people who want to get the informant's reward announced by Sapna's father Randhir Singh Chauhan; and going through some comic as well as dangerous interludes the screen couple arrive at the climax on their way to Phulwari.
[4] With Laxmikant-Pyarelal's music and Anand Bakshi's lyrics, Mohammed Rafi sang some fabulous songs for Shashi Kapoor.
