In 1957, Indiana Jones and his
long-time partner George "Mac" McHale are kidnapped by a group of Soviet
agents led by the psychic Colonel Dr. Irina Spalko. The Soviets infiltrate
a government warehouse in Nevada and force Indiana to find a crate
containing the remains of an extraterrestrial life form that crashed ten
years prior in Roswell, New Mexico. After finding the crate, Mac
double-crosses Indiana, having been bought off by the Soviets. Indiana
manages to escape into the desert, where he stumbles upon a nuclear test
town and survives a nuclear explosion by hiding in a lead-lined
refrigerator. He is later found and debriefed by the FBI because of Mac's
Soviet ties. Shortly after returning to Marshall College, Indiana is
offered an indefinite leave of absence to avoid being fired because of the
incident.
At a train station, Indiana is stopped by greaser Mutt Williams, who tells
him that his old colleague Harold Oxley was kidnapped after discovering a
crystal skull in Peru. Indiana proceeds to tell Mutt the legend of a skull
found in the mystical city of Akator, in which whoever returns the skull
to the city would be given control over its supernatural powers. Mutt
gives Indiana a letter from his mother, who was also kidnapped, containing
a riddle written by Oxley in an ancient Native American language, which
leads them to the Nazca Lines in Peru. There they discover that Oxley was
incarcerated in a psychiatric hospital, having suffered a mental breakdown
from the powers of the skull, until he was kidnapped by the Soviets. In
Oxley's cell, they find clues that lead them to the grave of Francisco de
Orellana, a Conquistador who went missing in the 16th century while
searching for Akator. They discover the skull at the grave, with Indiana
reasoning that Oxley had hidden it there after finding it.
Shortly afterward, Indiana and Mutt are captured by the Soviets and taken
to their camp in Brazil, where they find Oxley and Mutt's mother, who
turns out to be Indiana's old love, Marion Ravenwood, and reveals that
Mutt is Indiana's son. Spalko believes that the crystal skull belongs to
an extraterrestrial life form and holds great psychic power, and reveals
that the specimen stolen from the warehouse also has a crystal skull. She
also believes that returning the skull to Akator will grant the Soviets
the advantage of psychic warfare. Indiana, Marion, Mutt and Oxley manage
to escape from the Soviets into the Amazon, where Mac claims that he is
actually a CIA double agent working against the Soviets and joins the
group.
The five head for the temple of Akator, but not before being attacked by
the Soviets. They manage to escape when a colony of giant ants appear, and
try to eat them. They reach the temple, surving an attack by the Ugha
warriors defending it. As they enter the temple, Mac, who is actually
still loyal to the Soviets, secretly leaves a trail of homing devices for
the Soviets to follow. The five enter a chamber containing thirteen alien
crystal skeletons, one missing a skull, seated on thrones in a circle.
After the Soviets arrive, Spalko places the skull onto the headless
skeleton. The aliens begin communicating to the group through Oxley in an
ancient Mayan dialect, promising to reward them a "big gift". Spalko
approaches and demands to "know everything". The aliens grant her request
and transfer their collective knowledge into her mind, activating a portal
to another dimension. Indiana, Marion, Mutt and the now-sane Oxley escape
the temple, while Mac and the other Soviets are sucked into the portal;
the skeletons, meanwhile, form a single alien which overwhelms Spalko with
its knowledge, causing her brain to ignite and her body to disintegrate,
her scattered essence absorbed into the portal. The temple crumbles, and a
flying saucer rises from the debris and disappears to the "space between
spaces". After they return home, Indiana is reinstated and made an
associate dean at Marshall College, and he and Marion are married. |
