In 1936, archaeologist Indiana Jones braves an ancient booby-trapped temple in Peru and retrieves a golden idol. He is confronted by rival archaeologist Ren  Belloq and the indigenous Hovito people. Surrounded and outnumbered, Indy surrenders the idol to Belloq and escapes aboard a waiting floatplane.
Jones returns to his teaching position at Marshall College, where he is interviewed by two Army Intelligence agents. They inform him that the Nazis are searching for his old mentor, Abner Ravenwood, under whom Jones studied at the University of Chicago. The Nazis know that Ravenwood is the leading expert on the ancient city of Tanis in Egypt, and that he possesses the headpiece of the Staff of Ra. Jones deduces that the Nazis are searching for the Ark of the Covenant; the Nazis believe that if they acquire the Ark their armies will become invincible. The Staff of Ra is the key to finding the Well of Souls, a secret chamber in which the Ark is buried.
The agents authorize Jones to recover the Ark to prevent the Nazis from obtaining it. He travels to Nepal and discovers that Abner has died, and the headpiece is in the possession of Ravenwood's daughter Marion. Jones visits Marion at her tavern, where she reveals her bitter feelings toward him from a previous romantic affair. She physically rebuffs his offer to buy the headpiece, and Jones leaves. Shortly after, a group of thugs arrive with their Nazi commander, Arnold Toht. Toht threatens Marion to get the headpiece, but when Jones returns to the bar to fight the Nazis and save Marion, her bar is accidentally set on fire; during the fight, the headpiece ends up in the fire and Toht severely burns his hand trying to take the hot headpiece, and flees the tavern screaming. Indy and Marion escape with the headpiece, and Marion decides to accompany Indy in his search for the Ark so he can repay his debt to her.
The pair travels to Cairo, where they meet up with Indy's friend Sallah, a skilled excavator. Sallah informs them that Belloq and the Nazis are digging for the Well of Souls with a replica of the headpiece (created from the scar on Toht's hand). They quickly realize the Nazi headpiece is incomplete and that the Nazis are digging in the wrong place. The Nazis kidnap Marion and it appears to Jones that she is killed in an exploding truck. After a confrontation with Belloq in a local bar, Indy and Sallah infiltrate the Nazi dig site and use their staff to correctly locate the Ark. Indy discovers Marion is alive, bound and gagged in a tent, but does not release her for fear of blowing his cover. Indy, Sallah, and a small group of diggers unearth the Well of Souls and acquire the Ark. Belloq and Nazi officer Colonel Dietrich arrive, seize the Ark from Jones, throwing Marion into the Well of Souls with him before sealing it back up. Jones and Marion escape to a local airstrip, where Jones has a fistfight with a Nazi mechanic and destroys the flying wing that was to transport the Ark to Berlin. The panicked Nazis remove the Ark in a truck and set off for Cairo, but Jones catches them and retakes it. He makes arrangements to take the Ark to London aboard a tramp steamer.
The next day, a Nazi U-boat appears and intercepts the ship. Belloq and Dietrich seize the Ark and Marion but cannot locate Jones, who stows away aboard the boat and travels with them to an island in the Aegean Sea. Once there, Belloq plans to test the power of the Ark before presenting it to Hitler. Jones reveals himself and threatens to destroy the Ark with a panzerfaust, but Belloq calls his bluff and Jones surrenders rather than destroy such an important historical artifact. The Nazis take Indy and Marion to an area where the Ark will be opened and tie them to a post to observe. Belloq performs a ceremonial opening of the Ark, which appears to contain nothing but sand, all that remains of the Ten Commandments. Suddenly, angelic ghost-like beings emerge from the Ark. Indy cautions Marion to keep her eyes closed and not to observe what happens next. Belloq and the others look on in astonishment as the apparitions are suddenly revealed to be angels of death. A vortex of flame forms above the Ark and shoots bolts of fiery energy into the gathered Nazi soldiers, killing them all. As Belloq, Toht and Dietrich all scream in terror, the Ark turns its fury on them: Dietrich's head shrivels up, Toht's face is melted off his skull and Belloq's head explodes. Flames then engulf the remains of the doomed assembly, save for Indy and Marion, and the pillar of fire rises into the sky. The Ark's lid is blasted high into the air before dropping back down onto the Ark and sealing it. Jones and Marion find their ropes burned off and embrace.
In Washington, D.C., the Army Intelligence agents inform Jones and Marcus Brody that the Ark is someplace safe and will be studied by "top men". The Ark is shown being stored in a giant government warehouse among countless similar crates.
