The story takes place in the near future, with the frame of the city of Rio de Janeiro shaken by social convulsions. The city has seen its main roads destroyed by mysterious attacks and is isolated from the rest of the country. To accomplish his mission, Marlon will travel in a small boat, embarking on a dangerous journey through Guanabara Bay, through small swamp canals, favelas, water pollution and open-air dumps. Far, far from the beautiful postcards of Rio. At the end of his mission, Marlon finds Kurtz, who has become the leader of a messianic paramilitary militia whose followers believe he is the reincarnation of Exu, an Umbandista god, whose mission is to break the cycle of misery and violence caused by drug trafficking in Rio.
