In the eighteenth film in the series, in late 1918, the Great War may have ended, but a new adventure begins for Indy when a mysterious man's dying words send him and Remy on a thrilling treasure hunt for one of Alexander the Great's most treasured possessions. Pursued by a dangerous one-eyed man, Indy follows the trail of the diamond from London to Alexandria to the South Seas where he has a run-ins with murderous Chinese pirates, is captured by savage headhunters, and meets anthropologist Bronislaw Malinowski.
