Deep in the Amazon, the population of the pink river dolphin is dwindling. Docile and easy to catch, the animal is being hunted to extinction and used as bait for scavenger fish. But two activists are each working tirelessly to raise awareness and protect the species. On the one hand a marine biologist and on the other a famous TV star, each has their own very different approach to their one common goal.

“Director Mark Grieco grabs our attention by going beyond the obvious… transforming A River Below into an unexpectedly compelling proposition” - Screen.
