Traveling through the lush, African Okavanga Delta on a documentary film-making expedition, the Planeteers come across a makeshift dam, and pipelines which are diverting the life-giving water away from the delta, leaving it a parched desert. In their ultralight planes, the Planeteers and their friend Rick search for the culprits. But when they are shot down by the Eco-villains, it could mean the end of the line for our heroes!
