Twenty-seven whole years after the hunt for the Ark of the Covenant in Raiders of the Lost Ark (1981), and nineteen years after the search for the Holy Grail in Indiana Jones and the Last Crusade (1989), the indefatigable professor of archaeology, Dr Indiana Jones, is finally back in action. This time, in 1957, already ten years into the Cold War, the cocky, Harley-Davidson-riding young greaser, Mutt Williams, enlists the help of Jones to locate the whereabouts of Indy's friend, Professor Oxley. Before long, a dangerous quest for the mysterious Crystal Skull of Akator, a pre-Columbian artefact made of diaphanous quartz, will drag the explorers in the impenetrable jungles of Peru and the fabled Lost City of Gold, as a murderous squad of Soviets led by the obsessed military scientist, Irina Spalko, are hot on their trail. However, what started as a time-sensitive rescue mission, will soon turn into an adrenaline-charged treasure hunt. Is Indy prepared for the secret of the ancient temple?
