1936 - When his old friend Marcus Brody and the US Government discover a Nazi excavation in Egypt, they pay a visit to Dr. Indiana Jones to find out what the Nazis seek. Indiana Jones quickly realizes that the Nazis, aided by Indy's old rival Rene Belloq, have discovered the ancient city of Tanis, which holds a Map Room revealing the location of the Well of the Souls - the resting place for the Ark of the Covenant. Said to house the Ten Commandments and grant incredible power to the one who can open it, the Ark would allow the Nazis to destroy vast stretches of the world.
To find the Ark before the Nazis, Indy must retrieve the medallion headpiece of the Staff of Ra from his old girlfriend Marion Ravenwood, unaware that Nazi agent Toht is following close behind. The two men cross path in a fiery brawl that leaves one side of the medallion's carvings burned into Toht's palm, the medallion safe with Marion. Traveling to Egypt, Marion and Indy seek the help of Indy's old friend Sallah, while Belloq attempts to read Toht's injury as a map to the Ark.
After translating the medallion's carvings, Indiana Jones enters the Map Room and places the medallion atop the Staff of Ra. Positioning the staff, Indy waits for sunrise, and as the first rays shine through the medallion's jeweled center and onto the model city of Tanis that lays over the Map Room floor, a beam of light pinpoints the Ark's resting place within the Well of the Souls. One step ahead of the Nazis, Indy and Sallah begin excavating the well and uncover the Ark with the Nazi's close on their tail.
It doesn't take long for Belloq to realize the missing pieces of the medallion's puzzle. The Ark of the Covenant unearthed and the Nazi's in close pursuit, a struggle begins that would ultimately land the relic and Marion in the wrong hands. Indy closes in on Marion and the Ark, only to be captured himself. In their rush to unleash the relic's incredible power, Belloq and the Nazis have forgotten the Ark's sacred requirements and soon find out the weight of their impatience.
