Many centuries ago there was a evil damyaan who was granted immortality by a (book of magi).But with that wish, he was also given a curse that he would be confined to the City of Sonapur.Therefore he lures the Raja Indravarma by telling him about the treasure of gold , where raja and Bheem were captured. And the only way for bheem and his friends to defeat damyaan is to destroy him along with (book of magi).
