Maharani Meenakshi is a princess who one day while out hunting is rescued from a handful of attackers by a hunter-warrior Jwala Singh (Pran) who lives alone in the jungle, accompanied only by his pet falcon, Sheroo.
She offers him a reward for saving her life but he only wants her hand in marriage which he had been denied by her father. During the night they are awoken by another tiger and Jwala goes to slay it. The tiger kills a villager and Jwala puts his poncho over him to cover his dead body. He wrestles the tiger and they both fall over a cliff. Tne Princess sees the body of the dead villager and she thinks it is that of Jwala and goes into shock. Her father eventually marries her off into another royal family. Unbeknownst to Jwala, Meenakshi is pregnant by him.
King Satpal Singh, Meenakshi's brother is told in a prophecy that he will be killed by his eldest nephew, Dharam. In order to prevent this, he pleads poverty and moves in with his sister.
The Queen gives birth to a healthy baby boy. Satpal takes the baby, minutes after it is born and tosses it out of a window. Instead of falling to its death though, the baby is caught by Sheroo who flies him to his master. Jwala has been injured by a tiger and is being healed by a poor blacksmith and his wife. They are childless and are pleased when the bird brings the baby, believing it to be a gift. They explain what happened to Jwala when he awakes and he assents to them keeping the child and raising it as their own.
In the meanwhile we learn than the Queen gave birth to twins and Satpal only dealt with the first born. He is satisfied that the prophecy has been averted and now plans to help himself further by swapping his sisters baby with his own. Whilst he is asleep though, his wife swaps the children back.
As the children grow up, Satpal mistreats his own child, who he believes to be the prince, and dotes on the prince whom he thinks is his own son.
The twins grow up. The elder is called Dharam (Dharmendra) and grows up to be a blacksmith like his father. The younger, Veer (Jeetendra) is the crown prince. The boys become best friends and do not realise that this is because they are actually twin brothers.
The story follows some of their adventures and their attempts to find love. Dharam falls in love with a princess (Zeenat Aman) while Veer wins the heart of a gypsy girl, Rupa (Neetu Singh). They also meet Jwala Singh who is the master of swordsmanship. Jwala Singh teaches Dharam the skills of swordsmanship and as a result Dharam also becomes a master swordsman. The training scenes were exceptional.
Once the truth about his son is revealed to Satpal, he attempts to get rid of Veer. Before doing so, he realises he must first break the bond between him and his staunchest supporter, Dharam.
The Kingdom has "an eye for an eye" as the ultimate law. Dharam's father is accused of shoddily preparing a chariot wheel which caused a soldier to lose his hands. In reality Satpal and his son Ranjeet sabotaged it. The Queen is forced to chop of Dharam's father's hands in retribution. Dharam vows never to forgive Veer for this.
Satpal and his son then kill Dharam's mother and use one of the prince's royal arrows. Dharam fins this and accuses the prince of the murder. In retribution for the mother he has lost, Dharam demands the Queen become his mother. Although Veer strongly protests, the Queen submits stating that she must be seen to uphold the law or no-one will. For this act, Veer begins to bitterly hate Dharam.
Veer challenges Dharam to a duel and Dharam accepts. Satpal and his son know that in this duet, Dharam will kill Veer and they will get Dharam executed for Veer's murder. Whilst the boys are fighting, the poor blacksmith reveals the story of how Dharam came to him and his wife. He shows the Queen the cloth the baby was wrapped in. The queen realises that this was in fact her own child who she believed to have been carried off by a falcon. She stops the fight just in time to stop the brothers from killing each other and reveals their relationship.
Reunited, the brothers now face the challenge of disposing of the forces that Satpal Singh has gathered together. In the end, Satpal is killed by Dharam.
