Widowed Mrs. Lal lives with her two sons, Ram and Ratan; an unmarried daughter, Sheela; Ram's wife, Parvati and her children. While Ram is employed in a mill, Ratan is studying engineering in Calcutta. When Ratan returns, he is offered a job at the same mill, falls in love with a Typist named Manju, much to chagrin of Malti, the daughter of the mill-owner, Sewakram. When Ratan finds out that Sewakram has been defrauding the employees, he decides to form a union, a move that is opposed by Ram, who is very devoted and loyal to Sewakram.
