Mandí is a fisherman from the Manao people, who live in the Amazon, in 1723. One day, he saves a huge turtle that is trapped in one of his fishing traps. In gratitude, she invites Mandí to the frog party, which will take place in the underwater world of Rio Negro. Spoken in the Baniwa language, Adeus, Querido Mandí is an Amazonian adaptation of the Japanese myth of Urashima Tarot.
