During the Cold War, Soviet agents watch Professor Henry Jones when a young man brings him a coded message from an aged, demented colleague, Henry Oxley. Led by the brilliant Irina Spalko, the Soviets tail Jones and the young man, Mutt, to Peru. With Oxley's code, they find a legendary skull made of a single piece of quartz. If Jones can deliver the skull to its rightful place, all may be well; but if Irina takes it to its origin, she'll gain powers that could endanger the West. Aging professor and young buck join forces with a woman from Jones's past to face the dangers of the jungle, Russia, and the supernatural.

Producer Frank Marshall stated that the film would be shot the same way as the previous three - with stunt men, and using CGI only when necessary. Before the film entered production Spielberg corroborated these claims, but during filming the decision was made to employ more CGI than had originally been anticipated. (Spielberg estimated at the time that about 30% of VFX would have to be CGI.

Mutt Williams:
What are you, like, 80?
