Wealthy Bombay-based industrialist Kedarnath travels to a small town where his childhood friend Narayan resides. He meets with him, his wife Laxmi, and their daughter Rani. He proposes that Rani marry his son Rajesh and move with him to the city. Narayan and Laxmi are overjoyed, and soon a marriage takes place. When Rani reaches Kedarnath's house, she is not at all welcomed by her mother-in-law Sheila, nor her husband or his sisters Jyoti and Pinky. She is ill-treated, belittled, slapped, and humiliated on every possible occasion. Then the unexpected happens: Jyoti happened to be a child bride married into a poor Bhardwaj family. Now Deepak Bhardwaj has grown up and come to claim Jyoti as his wife, and moves into their house, much to the chagrin of Jyoti, Rajesh, Pinky, and Sheila. Tragedy follows as Kedarnath passes away, leaving Rani and Deepak to the mercy of Sheila, who loses no time asking them to leave the house. She is now busy preparing Rajesh's marriage to a young woman named Sona, who is not only rich, but beautiful and ready to come to her home with a huge dowry. What Sheila does not know that Sona has her own agenda, which includes Sheila not at all.
