Set during the Cold War, the Soviets—led by sword-wielding Irina Spalko—are in search of a crystal skull which has supernatural powers related to a mystical Lost City of Gold. Indy is coerced to head to Peru at the behest of a young man whose friend—and Indy's colleague—Professor Oxley has been captured for his knowledge of the skull's whereabouts.

A man becomes increasingly jealous of his friend's newfound success.

Reuben Feffer is a guy who's spent his entire life playing it safe. Polly Prince is irresistible as a free-spirit who lives for the thrill of the moment. When these two comically mismatched souls collide, Reuben's world is turned upside down, as he makes an uproarious attempt to change his life from middle-of-the-road to totally-out-there.
