Set in the Marwar region in 1818 and addresses the notorious 'Gola' system of slavery. The fantasy adventure, leavened with realistic scenes showing the slaves' working conditions, tells of Kumar Umedhsingh of Kadeempur who institutes a usurious tax mainly to obtain power over the beautiful peasant girl Kamalbala. However, she is protected by Kartarsingh of Amargarh, whom she once nursed to health and who has vowed to liberate all slaves. Karatarsingh is imprisoned but eventually defeats the villain and rescues the heroine. A (presumably Rajput) emperor arrives, censures the villain and lets the lovers marry.
