The story is centered around the squabbling Sharma family, headed by their eccentric Daduji (Harindranath Chattopadhyay), which has a dubious reputation of the inability to retain a cook for more than a few months due to their ill treatment of their domestic helps. The family's disrepute spreads to such an extent that no person wants to be employed as a cook in their home, named Shanti Niwas (abode of peace). Then one day a young man named Raghu (Rajesh Khanna) offers to work as a cook, and is hired. Raghu, however, lives up to this challenge and becomes the apple of the eye of every inmate of Shanti Niwas. He even defuses the internal squabbles and re-unites the family. But is Raghu's slate clean, or is there more to his character?
