On a mission to expose environmental crimes in the rural areas of Northern Argentina, idealistic scientist Valentina travels to the swamp town of Corrientes to test the local water supply. Relying on remote support from her student Nina, who’s analyzing the data from her potentially contaminated samples, Valentina embarks on a quest into the dangerous Iberá wetlands. Meanwhile, Valentina’s husband Diego and his research partner Simon are on an expedition of their own at the South Pole, but their work is interrupted by the news
that something’s gone wrong for Valentina. As they rush to the wetlands, hoping they are not too late to keep her safe, evidence of an ecological cover-up comes to light — as does the truth about a love triangle that threatens to break the bond of trust between Diego and Simon.
