Kathy, Fuchs and Merlin are now exploring the savannah, looking for the Remington expedition. With them is Tom, the young native guide - and sole apparent survivor - of the American writer's party, who recounts the terrifying events that led him to run away. When Kathy and her companions finally discover Remington's base camp, though, they find no trace of unusual animals - or bodies. But they're quickly confronted to a series of increasingly weird events.
