Inspired by the legend that explains the formation of the majestic Iguazu Falls, this is a film about love, innocence, and the consequences of choices. Long ago, the Iguazu River flowed calmly, without waterfalls. Tarobá, a young indigenous warrior, was in love with Naipi, the beautiful daughter of Chief Igobi. When Naipi is chosen to be offered as a sacrifice to the powerful serpent-god M'boi, Tarobá faces a decision: to give up his love in devotion to the god or to fight to remain by Naipi's side, even if it means facing an eternal destiny.
