The film stars Om Prakash, Navin Nischol, Archana, Sonia Sahni, Deven Verma, Aruna Irani, Asit Sen and Lalita Pawar for the first time in a very different positive role. The music is by R.D. Burman and the lyrics by Majrooh Sultanpuri.
Unemployed slackers Bhola (Deven Verma) and Ajay (Navin Nischol) come across a newspaper advertisement about a missing elderly gentleman (Om Prakash), whose estate is worth millions. They find him in the Hanging Garden Park in Bombay and decide to make him their paternal uncle. They take him to live with them in a rented apartment, which they cannot afford. This elderly man, Girdharilal Om Prakash, takes an unusual interest in Ajay's girlfriend, Deepa (Archana).
While Bhola and Ajay try to find ways and means of getting rich by turning Girdharilal in, a number of horrific homicides are committed, all against former business associates of Girdharilal, and the clues all point toward the hapless duo.
