Off the coast of Liberia, a cluster of mangrove islands holds a colony of chimpanzees left behind when a New York blood-research lab shut down its testing program. The film follows the animals as they navigate a landscape of collapsed infrastructure and two civil wars, having survived medical experimentation only to be abandoned without food or care once the funding disappeared. Caretakers and former lab workers describe how a local nonprofit stepped in to keep the chimps fed on the islands, ferrying supplies across the water on a routine that has continued for years. Footage shows the animals foraging, forming social groups, and reacting to the humans who visit, offering a rare look at chimpanzees who once lived in cages now living semi-wild. The film traces the history of the lab itself, the outbreak of civil conflict that upended everything around the chimps, and the question of who is responsible for animals used in research once the research ends.
