The film was Padmini's debut film as a heroine. She had earlier worked as a child artist and as a supporting actress in Insaaf Ka Tarazu.

The music, composed by Rahul Dev Burman with lyrics by Majrooh Sultanpuri, was successful, but the movie itself did not have the success associated with a Nasir Hussain production, with his last three films being major hits (Hum Kisise Kum Naheen, Yaadon Ki Baraat and Caravan.)

The film took scenes from all previous Nasir Hussain productions and redid them as a part of the story, including the train top song (song being different) from his first production Jab Pyar Kisi Se Hota Hai, the runaway girl from Caravan and the song contest from Hum Kisise Kum Naheen.

Wealthy industrialist, Nanda, is enraged when he finds out that his eldest son, Ramesh, has fallen in love with a poor woman, Seema, and wants to marry her. He asks his son that if he marries her, he will exclude him from his will. In answer to that, Ramesh marries Seema and leaves the Nanda household. When Nanda's younger son, Ravi, returns home, he is told that his brother is away on business. Ravi does find out that Ramesh had been asked to leave by their father. He manages to convince his dad to change his mind about Ramesh, and sets off to find Ramesh. He finds out that Ramesh and Seema are no longer alive, but Seema had given birth to a son, and left him in the care of her sister, Kanchan. Ravi meets Kanchan, and both fall in love with each other. When Kanchan finds out that Ravi is Nanda's son, she is angry, and refuses to have to do anything with Ravi, as she is sure that she too will be rejected by Nanda, when he finds out that she is poor, and related to Seema. What Ravi and Kanchan don't know that Nanda has an ulterior motive, as he wants to adopt Ramesh's son - by hook or by crook.

Notable songs

The most well known song from the film is "Puchho Na Yaar Kya Hua" by Mohammad Rafi and Asha Bhosle. The melodious song was a major hit in India at the time.

In recent years, the soundtrack has received attention for "Dil Lena Khel Hai Dildar Ka," a synthesized, minimalist, electronic dance/disco song. It has been described as having "a very futuristic electro feel" and approaching a "techno wavelength." The song has been cited as a possible influence on the 1982 proto-acid house album Synthesizing: Ten Ragas to a Disco Beat by Charanjit Singh.
