In 1957, Colonel-Doctor Irina Spalko and a convoy of Soviet agents posing as U.S. soldiers infiltrate a military base in the Nevada desert. They have captured archeologist Indiana Jones and force him to lead them to a crate in "Hangar 51", which holds the remains of an extraterrestrial creature that crashed ten years before in Roswell, New Mexico. Indy uses both gun powder and shot to find the crate, which has magnetic properties. Indiana attempts to escape but is foiled by his partner Mac, who reveals that he is working with the Soviets. After a fight and an elaborate vehicle chase through the warehouse, Indiana escapes on a rocket sled into the desert, where he stumbles upon a nuclear test town and survives a nuclear blast by hiding in a lead-lined refrigerator.

Soviet agents approach them, and a chase commences on the college grounds. Indiana realizes that the Soviets were trailing Mutt to get him to decode Oxley's letter.In Peru, Indiana and Mutt discover that Oxley was locked in a church-operated psychiatric hospital until the Soviets kidnapped him.

Indiana finds the crystal skull that Oxley hid in Orellana's grave. The Soviets capture Indiana and Mutt and take them to the camp where they are holding Oxley, as well as Mutt's mother (and Indiana's ex-lover), Marion...
