The film opens in 2016 BCE with Sarman, a young man from the village of Amri, who lost his parents at a young age. Sarman kills a crocodile that has been terrorizing his village's fishermen and is hailed as a hero. He asks his uncle, Durjan, to allow him to go to Mohenjo Daro to trade their family's goods, but his uncle refuses. Sarman attempts to sneak away to the city at night with his friend Hojo, but is caught by Durjan, who relents and allows both friends to go. He gives Sarman a seal that contains an inscription of a unicorn that Sarman often sees in his dreams, suggesting he use it only once in a life or death situation.
