Narendra Sahay a.k.a. "Naren" is the son of Jeeva Sahay, a rich politician in
Calcutta. Naren visits
Gangotri to study the source of the
holy river Ganga, and to get some holy water for his wheelchair-using paternal grandmother. There, he meets a very pretty girl named Ganga Singh. Ganga lives near Gangotri with her brother, Karam. Naren sees Ganga bathing in a white saree under the waterfall and she later helps him to collect the holy water. Soon, they fall in love, decide to marry and sleep together. They are happily married but Naren has to return to Calcutta as he wanted to convince his parents about accepting Ganga as their daughter-in-law. He promises Ganga that he will soon return to her. Ganga is pregnant with Naren's child and she gives birth to a son. She faces many problems because of her child as well as her beauty. Her brother Karam is killed and Ganga finds herself alone. Finally deciding to go to her husband, Ganga travels from Gangotri to Calcutta. However, the journey is fraught with hardship and misadventures. She makes it as far as
Benaras, and is helped by police with a ticket to Calcutta. However, she falls into the clutches of a man who lures her to a brothel. Bhagwat Choudhary, a rich politician, buys Ganga and brings her to his "bagan bari" (house near a garden) as a concubine. Bhagwat has arranged for his daughter, Radha to wed to Naren, who was informed that Ganga is dead. However, Naren's maternal uncle, Kunj Bihari, finds Ganga in Bhagwat's bagan bari and learns her story. He asks her to appear at her husband's wedding to test if her husband can recognize her or not. Naren recognizes Ganga at the ceremony. However, his father refuses to accept Ganga as his daughter-in-law. Naren also finds out about his son and the three try to leave. However, Bhagwat Choudhary shoots Ganga in a fit of rage, causing Naren to thrash Bhagwat Choudhary. Radha then informs him that Ganga has survived and Naren leaves with Ganga and their son to live by the river Ganga. ==Cast==
