Three characters lives become intertwined when they meet on the Atlantic side of the Amazon — Janalice, a victim of human trafficking; Preá, who must make peace with his fate as the leader of a local criminal organization known as the "water rats"; and Mariangel, who is seeking to avenge the deaths of her family. All three of them must try to break the curse, or "pssica," that they believe has been cast on them.
