What Leads Up to the Ending
Karen Ross, working for a company called ERTS, leads an expedition to find blue diamonds that are valuable for computer technology after her earlier team was killed. She joins Elliot, a primatologist, and Amy, a gorilla who communicates with sign language, and Captain Munro, a mercenary guide.
What Happens at the End of Congo
In the ruins of Zinj, the team finds hieroglyph-like carvings showing that the ancient people trained a breed of gray gorillas to guard their diamond mines. The gorillas still follow their training and attack the camp at night, killing several porters. Amy uses sign language to understand them, and the team uses laser-sighted weapons and a recorded sign to defend themselves. Ross, desperate to get the diamonds, tries to call in an air strike, and Mount Mukenko erupts, burying the city. The team flees, carrying only a handful of diamonds. Elliot later releases Amy back into the wild, and she joins a gorilla band.
