In 1939, somewhere off the coast of Greenland, an American research vessel discovers an enormous iceberg inhabited by an obsessive Dr. van Hesling, who believes the ancient ship of the Gods to be buried beneath the ice. Months later, an international research team led by Indiana Jones returns to the giant iceberg, named Odinsland, to uncover its secrets locked within.

Washington, Russian embassy: The beautiful Soviet commissioner Tamara Jaglova invites Indiana Jones to take part in an expedition to Outer Mongolia, where the legendary Sword of Kahn is being sought out in the hopes of restoring the Mongolian Empire to its former glory. Indy must compete with rivals from Russia, China, Germany and Japan in a race to find the sword that will span several continents.

In Chicago of yesteryear, one must be prepared for anything. Killers and thugs are around every sleazy corner. It's no wonder then that Indiana Jones finds himself in cement overshoes shortly after colleague Professor Petryk makes a sensational discovery.   A young Mormon, Zach, wants to sell Indy an old clay disk which belonged to the vanished culture of the Anasazi Indians. Fleeing from Chicago's criminal underground, Indiana Jones and his friends get caught up in an adventure of unexpected proportions within an ancient city of the legendary culture.

Indiana Jones travels to South America looking for an American geologist who's gone missing. Locating him in a tiny village at the foot of the Andes that's surrounded by strange natives, the geologist gives Indy a golden talisman -- the Feathered Serpent -- before dying from illness. Indy learns that the Feathered Serpent belongs to the Mayan High Priest, and is reputed to bestow its owner with tremendous magical powers. On the run from a hostile tribe who wants the talisman back, Indy must escape before the natives -- or the talisman -- do him in!

Odd coincidences abound: Near England's coast a submarine is rammed by an incredibly ancient boat. Near Liverpool a man is found who speaks a bizarre unknown language. And near Ghent, a Belgian and a German are studying a mysterious castle from the Middle Ages.   It's 1940, and Indiana Jones is on the run from a Nazi henchman and a young Belgian resistance fighter -- until he discovers that these strange occurrences are all related to the sword Excalibur, the legendary sword of Arthur Pendragon, fabled King of Britain.

Indiana Jones is a man who does not forget. Sixteen years ago, Professor Basil Smith saved his life, and now its Indy's chance to repay the debt. Receiving a wire from Smith in Istanbul, Indy quickly makes the trip to Turkey but arrives to find the professor missing. With clues leading him to Egypt, Indiana Jones meets an ancient, cruel force in the shadows of the pyramids that has waited for millennia to be released.

While in Washington, Indiana Jones is asked by a certain Mr. Franklin and Mr. Delano to take an expedition to Easter Island -- an expedition, Indy suspects, that won't be a pleasant research trip.   There's something odd about Franklin and Delano -- they simply grin too much. One of their agents on the trail of German conspirators has gone missing and Indiana Jones needs to find him. His search starts on the atoll Pau-Pau, but this tropical isle is deceiving -- Polynesia may be a hell decorated with flowers on this suicidal mission.
