The film opens with a wealthy man liquidating his African estate and turning the proceeds into diamonds, which he keeps in a belt as he boards a flight to India. In a tragic turn, he suffers a fatal heart attack in the washroom and, in his last moments, entrusts a fellow passenger with delivering the belt to his son, Rajesh, who works as a singer-dancer-entertainer at the Ashoka Hotel in Delhi. The fortunate companion turns out to be a wealthy businessman, Kishorilal, a man whose luck and wealth have grown in the years since.
Flashbacks reveal how, years earlier, Kajal’s father Kishorilal found himself in dire financial straits and was sheltered by Sanjay’s father, a bond that eventually left Kishorilal with immense wealth. The long-promised marriage between Sanjay and Kajal seemed secure at first, but that promise falls apart when Kishorilal insults them and forgets the arrangement born from that old favor.
Soon after, Kishorilal comes under the relentless pursuit of goons who are after the diamond belt. He narrowly escapes and heads to Delhi, only to realize the danger is waiting for him at the airport. Fleeing, he slips into a cycle shed and hides the belt inside the toolbox of a bicycle, vanishing from sight. The bicycle, owned by Sanjay Kumar, becomes the vehicle for a dangerous misdirection, as Sanjay wheels away unaware that his cycle contains 25 crore rupees in diamonds. The pursuers, led by the scheming Saudagar Singh, are determined to recover the loot.
With Kishorilal out of reach, Saudagar Singh and his partner Baljit Kumar Dana devise a trap for Rajesh, spinning a false tale that Kishorilal has kidnapped Saudagar Singh’s son, Ramesh. Believing the story, Rajesh hatches a reckless plan to abduct Kajal under the pretense of love, hoping to force Kishorilal to surrender the diamonds. Meanwhile, Sanjay Kumar steps into a managerial role for a woman named Manjeet and stages a romantic ruse with Kajal, who actually harbors love for her childhood friend. The paths of love and deceit cross in a series of meetings between Rajesh and Kajal, while the web of lies grows thicker.
As the plot thickens, Saudagar uses Manjeet to harvest the diamonds, bringing Kajal along to seal the deal. Kajal is ultimately rescued by Rajesh and Sanjay, and the trio escapes together. A climactic confrontation at the country’s border ensues, and in the skirmish, Sanjay is wounded by Saudagar. After threatening Kajal, Sanjay survives the ordeal and, seizing the moment, shoots Saudagar dead before the police can intervene. In the aftermath, Sanjay and Kajal begin a new life together, while Rajesh finds happiness with his former fiancée, who had run away from her own wedding to be with him.
