Sooryavansham is a story about Thakur Bhanu Pratap Singh, who rules his region with fairness and respect for his subjects. He lives with his wife Sharda and three sons, with Heera being the youngest. Heera, who is uneducated, is black-listed by his father for his actions.
When Heera abducts a girl named Radha and marries her, it brings shame to the family and prompts Bhanu Pratap to kick him out of the house. Heera and Radha struggle to make ends meet, but with the introduction of a bus service, Heera becomes wealthy and Radha becomes a collector.
Heera continues to succeed by opening a charitable hospital in his father's name, but faces another setback when he is accused of poisoning his father's Kheer.
