The film's music director was S. D. Burman and the lyrics were written by Sahir Ludhianvi.

[1] Mangal (Dev Anand) is a taxi driver who is called "Hero" by his friends because of his altruistic habits.

He is a driver who drives a cab by day, then at night listens to the seductive club dancer Sylvie (Sheila Ramani) who has feelings for him.

Mangal gallantly rescues her, and attempts to take her to her destination, but to no avail, as the person she is looking for is Ratanlal, a music director, and he has moved out.

Dev Anand's taxi in the movie was a 1947 Chevrolet Fleetmaster 4-Door Sport Sedan.
