The Kratts visit Uganda to compare the lives of two bands of chimpanzees. First, they travel with the wild chimpanzees in the Ngamba and Kibate forests, witnessing their fascinating behavior, including attacks on other primates. Then, the brothers spend time at the Ngamba Island Sanctuary, home to chimpanzees that have been rescued from civil war and poachers. Climbing into trees, the brothers swing awkwardly on rope, contrasting the abilities of the human primate with its closest relatives.
