Tere Ghar Ke Samne
The film deals with enmity between two rich businessmen -- one is Dev Anand's father (Om Prakash), the other is Nutan's father (Harindranath Chattopadhyaya). Both buy plots next to each other and want their respective homes to look better. How the young lovers get past their fathers' differences and unite is what the film is about.
The songs Dil ka bhawar kare pukar, the title track and Tu kahan is nashili raat mein are worth listening to.
