Filmmakers Marion Pöllmann and Rainer Bergomaz trace the Essequibo River across Guyana, from its source in the Acarai Mountains to the delta where it empties into the Atlantic, a run of roughly 1000 kilometers. The three-part series follows their expedition by boat and on foot through rainforest, rapids, and swamp, with stops in villages along the way where indigenous communities describe how the river shapes hunting, fishing, and travel in a country with almost no roads into its interior. The delta itself gets treated as its own ecosystem, a tangle of channels and mangroves the film calls one of the region's biodiversity hotspots. Cameras track macaws, caimans, and river dolphins alongside the physical toll of the journey itself, sudden weather, exhausting portages, and the logistics of moving equipment through terrain with no infrastructure. Filmed against the backdrop of Venezuela's territorial claims on the region, the series turns a geography dispute into a ground-level portrait of the river people actually live on.
