Dwarkanath, a wealthy resident of Darjeeling, welcomes home his only daughter, Anjana, who returns after completing her studies. The sophisticated young girl is strangely drawn to the gang of gypsies who work on the tea estates and live near Dearkanath's own palatial home in their humble bustees. Anjana meets Jhumroo, a happy-go-lucky gypsy boy, soon to fall in love......thus creating a dangerous rival in the gypsy beauty, Chamki, who has herself known and loved Jhumroo for as long as she can remember.
This socially unequal romance meets with the strong disapproval of Dwarkanath who has already selected Ramesh as his future son-in-law. He forbids Anjana to have anything to do with the gypsies, and specially with Jhumroo. Almost simultaneously, the Sarder of the gypsies himself forbids any thought of marriage that Jhumroo may entertain, with Anjana in view. As a future leader of the gypsies, Jhumroo cannot marry outside his own social order.
Dwarkanath hurriedly goes ahead with the marriage plans for Anjana with Ramesh, but unfortunately for him the good hearted Ramesh, though otherwise a weakling, learns where Anjana's feelings really lie, and winning over the fiery Chamki to his side, he plots the kidnapping of Anjana right form the wedding pandal. This daring act creates a sensation.
All at once, the engrossing story of "Jhumroo" unfolds in a riot of colour and action. What spell did the old gypsy woman Kamli hold over Dwarkanath? Who was the liquor imbibing Bihari and what did he know of Jhumroo's past? How can a great and sincere love overcome all barriers and obstacles? These answers, and many more, go to make up a smashing climax to a startling story.
