Nagraj, who is the vizier of Roopnager schemes to remove the princess Rupmati by killing her while she is on a hunt. The plan is foiled when a woodcutter named Bahadur (Hercules) intervenes and saves Rupmati from Nagraj’s curse by using his brute strength and a powerful talisman. Bahadur is hired by Nagraj to be a tax collector and is sent to Mayanagari where the queen awaits her chance to kill him with an exploding volcano and a horrible demon. In the meantime, Nagraj captures the princess and hides her away in a magic cave.
