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 force Indiana Jones 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. Jones 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, Jones escapes on a rocket sled into the desert, where he stumbles upon nuclear test town and survives a nuclear blast by hiding in a lead-lined refrigerator. While being debriefed, Jones discovers he is under FBI investigation because of Mac's Soviet ties. Jones returns to Marshall College, where he is offered a leave of absence to avoid being fired because of the investigation. While leaving, Jones is stopped by greaser Mutt Williams and told that his old colleague, Harold Oxley, disappeared after discovering a crystall skull near the Nazca lines in Peru.
