Indy, Marion, Mutt, Mac, and Oxley, carrying the skull, find their way into El Dorado, only to discover the crystal skeletons of the 13 beings, one of which is headless. Just as Oxley is about to set the skull on its respective body, Mac points a gun at Indy and Irina shows up. She takes the skull from Oxley and sets it on the body herself. The entity then begins talking through Oxley in Mayan saying that it will them a 'big gift'. Irina demands to 'know everything'. As the beings begin to channel their collective knowledge into Irina's mind, the walls of the chamber start to disintegrate and a portal to another dimension opens in the ceiling. Determined not to go out that way, Indy, Marion, Mutt, and Oxley escape through a tunnel and Max begins to pick up everything gold that he can carry, leaving Irina to face the beings by herself. The 13 skeletons then merge into one being, and Irina screams for them to stop feeding her knowledge...her mind has had enough. Suddenly, her eyes catch fire and she disintegrates into the portal. Water begins to fill the temple, and Indy and crew find themselves trapped at the bottom of a deep well. Treading water until they reach the top of the well, they are flushed out to safety. The valley below opens up, and a large spaceship emerges then disappears into the 'space between spaces', as Oxley puts it. Indy returns to Marshall College where he is reinstated and promoted to associate dean, and he and Marion are married. In the final scene, a gust of wind blows Indy's hat down the aisle, and Mutt picks it up. Just as he's about to put Indy's hat on his head, Indy walks past, takes the hat out of Mutt's hands, and puts it on his own head.
