Chaani exposes Maham's plan to use the gold from the Sindhu to enrich himself and to smuggle in weapons from the Sumerians. All the chiefs now stand against Maham. The people elect Sarman as the new chief but Sarman suggests Mohenjo Daro needs a people's government, not a chief. With the arrival of a heavy thunderstorm, Sarman realizes that the dam will burst and the Sindhu River will flood the city. He rallies the people to lash boats together and form a floating bridge. They evacuate Mohenjo Daro and cross to the other side of the river. The dam collapses, and Maham, chained in the city square, is drowned. The once renowned Mohenjo Daro is no more. The survivors migrate to another river, where Sarman sees the unicorn of his dreams and names the river Ganga.
