The Sooryavansham family head, Thakur Bhanu Pratap Singh, is the respected
sarpanch of the village of Bharatpur. He has rendered yeoman service not only to the people of Bharatpur but also to those of eighteen neighboring villages. He lives in a mansion with his wife Sharda and his three sons, Karan, Varun, and Heera. Heera, the youngest, is illiterate and therefore treated like a servant. Disliked by Bhanupratap, he is excluded from family matters and confined to menial tasks. Despite this treatment, Heera loves his father unconditionally and finds affection only from his mother and his friend Dharmendra (Mindra), a servant in the household. Days before the wedding of Bhanupratap's daughter, the groom arrives with his sister Radha. Mistaking Heera for a servant, Radha makes him run errands. On the wedding day, she is shocked to learn from her father that Heera is Bhanupratap’s son. Curious, she asks Mindra to tell her about Heera’s past. As a child, Heera consistently failed in school but continued attending to see Gauri, a girl adopted by Bhanupratap after her parents’ death. When a teacher beat Gauri, Heera quit studies altogether. Believing that Heera’s presence would hinder Gauri’s education, Bhanupratap sent her to a boarding school. When they grew up, Bhanupratap arranged their marriage. However, Gauri, unwilling to marry an illiterate man, attempted suicide. Heera saved her but accepted the blame, claiming he had refused the marriage. Bhanupratap misunderstood, thinking Heera harbored lust for Gauri, and his hatred for his son deepened. Gauri later married a wealthy man. Moved by Heera’s story, Radha proposes marriage to him, and he accepts. Meanwhile, Deshraj Thakur, another
zamindar in Bharatpur, aims to ruin Bhanupratap’s family by marrying Radha to his son Arjun. This would force Radha’s lawyer father to act in Deshraj’s favor, giving Deshraj an advantage over Bhanupratap. Radha’s mother approves the alliance and pressures Bhanupratap to separate Radha from Heera. Bhanupratap gives Heera an ultimatum: either marry Radha or regain his father’s respect. Encouraged by Mindra, Heera chooses Radha. On the wedding day, he elopes with her, angering Bhanupratap, who disowns him. Heera and Radha settle in Mindra’s house on the village outskirts. Heera works as a
labourer in a
transport company before starting his own transport business with money borrowed from Radha’s uncle, Ranjeet. Naming the company after his father, in time, Heera becomes wealthy and respected. At the same time, Radha clears the
UPSC examination and becomes an
IAS officer. The couple has a son, named after Heera’s father, and nicknamed him Sonu. Bhanupratap, however, continues to hate Heera despite his rise in status. Heera later fulfills his father’s dream of establishing a
hospital for the poor. At the inauguration, he publicly credits his success to Bhanupratap, believing his father had expelled him so he could learn to depend on himself. Bhanupratap, secretly present at the ceremony, overhears this. While reconsidering his actions, Bhanupratap encounters his grandson Sonu outside school and begins secretly spending time with him. Learning of this, Heera asks Sonu to give some
kheer to his “friend” the next time they meet. Meanwhile, Sharda pleads with Bhanupratap to reconcile with Heera. Bhanupratap, tormented by guilt, phones his son but collapses after coughing blood. He is hospitalized, and Deshraj accuses Heera of poisoning the kheer to kill his father. As Deshraj’s men assault Heera, Bhanupratap recovers and came to his son’s rescue. He reveals that the kheer had been poisoned by Deshraj himself. The father-son duo beat up Deshraj and his men until Deshraj confesses to his crime. Finally, with the family reuniting, Bhanupratap embraces Heera in front of all their relatives. ==Cast==
