Prakash was the younger step-brother of Kundanlal, the Zamindar of the village and Lali was the younger sister of Gangajali, the wife of Kundanlal; they were brought up under the same roof. Prakash and Lali loved each other but Gangajali remained a constant menace and opposition in their love, She hated Prakash and always blamed him for some other thing. There also lived a young Banya, Sunder who was also a love-lorn of Lali but Lali always hated him and made fool of him. One day Prakash was forced to leave the village due to the harsh words and ill-treatment of Gangajali.
Rajaram the greedy rich man of Lucknow and had two sons, Amarnath and Nandlal. Amarnath was a chronic T. B Patient and Nandlal was a spent up a child. Gangajali, on the suggestion of Champa (a woman from the same village who was in conspiracy with Rajaram), engaged Lali with Rajaram's son. Rajaram brought his ailing son Amarnath as the bridegroom in place of Nandlal in the Barat. The position became very serious and Kundanlal refused to marry Lali. Lali intervened and ended the matter by accepting Amarnath as her husband who was given to her by her sister.
Before the echo of the happy marriage bells faded, the world becomes gloomy for her. She became a widow. Rajaram's attitude towards her became very harsh. Kundan Lal and Gangajali came to fetch her from the village. Lali refused to go with them and decided to stay there and serve the family. This decision changed Rajaram but Nandlal, her brother-in-law, became a villain in her life. What Rajaram did in consultation with Thakur Sher Singh see that on the silver screen.
