To raise awareness for the rainforest, Professor Wiseman enlists George and the Man with the Yellow Hat to help make a movie about the different plants, animals, and insects that call it home. But when a frisky tamarin monkey runs off with their camera, the chase is on! George, Steve, Hundley, and Gnocchi get stuck in the back of a delivery truck after Steve steps inside in order to get out of the sun and see his handheld video game better. When the truck finally stops and George helps them escape, they are lost and must use their senses and memory to figure out how to get back home.
