Vedha Prajapati is a young orphan who indulges in pickpocketing for his livelihood. Vibha, a sanyasi whom Vedha is trying to woo, makes him realise that he is the prophesied protector of the nine sacred scriptures or grandhas of Emperor Ashoka.

After the Kalinga War, Emperor Ashoka turned his powers into the nine grandhas, which possess the power to turn mortals into deities.

The Black Sword, a ruthless group led by Mahabir Lama, seeks to claim the grandhas and plunge the world into darkness. He succeeds in capturing eight of the nine grandhas, becoming immensely powerful in the process. However, he fails to attain the ninth and most powerful of the grandhas, Amaragrandha. His quest for it clashes with Vedha, who is revealed to be the son of the protector of the same grandha, Ambika Prajapati.

To kill Mahabir Lama, Vedha then realises that he must attain the divine superweapon of Mirāi, which is later revealed to be the Kodanda of Lord Ram. The rest of the story unfolds as Vedha embarks on a journey to wield Mirāi, along with understanding his true identity and purpose.

In the post-climax scenes, a mysterious man is introduced and is revealed to have the power of Midas touch. He becomes obsessed with the powers of Mirāi, after learning about Mahabir Lama's death. Then he vows to seek the superweapon for his own enrichment and also states 'I will deliver the justice that was refused in Treta Yuga in this modern age', possibly hinting at a sequel.
