A famous Saigal musical narrating a strange love story set against 1930s industrialization and worker-management relations. The 16-year-old Prabhavati inherits a mill and turns it into an extremely profitable enterprise. Prakash is a worker who designs a more efficient machine for the factory for which he first gets sacked and then is re-employed. He falls in love with Prabhavati's sister Sheila, who later makes way for Prabhavati who is also in love with Prakash. Her withdrawal distresses Prakash, causing him to bully the workers who then go on strike.
