Concerned about the outbreak of plague in a distant rural village in India, Dr. D.D. Sinha asks a number of prominent doctors to go there and treat the ailing and prevent the disease from spreading. No one except his protégé, Dr. Paras, is prepared to go there. Dr. Paras travels there, works with the villagers to prevent the disease and treats the ailing, and is successful in preventing it's spreading to other communities. He meets with village belle, Lajwanti alias Lajjo, and both fall in love with each other.
