Indiana Jones and the Last Crusade

In 1912, Boy Scout Indiana Jones lives with his father Henry Jones Sr. in Moab, Utah. One day, while exploring caves on an excursion with his scout troop, Indy takes a crucifix owned by Francisco Vázquez de Coronado from a group of graverobbers led by a man named Garth, and after a brief chase on horseback and aboard a circus train, Indiana flees to his home, where Garth and his men find him and confiscate the crucifix with the help of the local sheriff. Garth, however, admits his respect for the scrappy young man, and gives him his fedora before leaving.
In 1938, Indiana successfully takes back the crucifix from the employer of the graverobbers off the Portuguese coast. After returning to his university classroom in the United States, Indiana learns his father has disappeared while searching for the Holy Grail and Henry's home was ransacked. Walter Donovan, his father's financial backer, tasks Indiana with finding both Henry and the Grail. Indiana receives a package containing Henry's diary, which includes his research on the Grail, and travels to Venice alongside Marcus Brody to meet Henry's associate Dr. Elsa Schneider. Beneath the library where Henry was last seen, Indiana and Elsa discover a catacomb containing an inscribed shield which reveals that the path to the Grail begins in Alexandretta. The two are subsequently attacked by a mysterious group who reveal themselves to be the secret Brotherhood of the Cruciform Sword, dedicated to protecting the Grail. After saving the group's leader Kazim, Indiana learns that Henry is being held at Brunwald Castle in Austria. Indiana entrusts Marcus with a map from the diary detailing a route to the Grail and sends him to Alexandretta to rendezvous with their old friend Sallah. Discovering their rooms have been ransacked, Indiana reveals the diary's existence to Elsa before they sleep together.
In Austria, Indiana and Elsa infiltrate the castle, discovering it to be under Nazi control commanded by Standartenführer Ernst Vogel. Indiana finds Henry and tries to escape, but surrenders after Vogel holds Elsa at gunpoint. She reveals herself and Donovan to be Nazi collaborators and takes the diary. After arriving in Alexandretta, Marcus is captured by the Nazis as well. Elsa returns to Germany, while Indiana and Henry escape the castle before traveling to Berlin, where Indiana retrieves the diary during a book burning rally hosted by Adolf Hitler. After recovering it from Elsa, Indiana and Henry flee on a Zeppelin. Soon the zeppelin reroutes back to Germany, forcing Indiana and his father to commandeer a spare plane before evading two Luftwaffe planes pursuing them.
Once Indiana and Henry arrive in Hatay, Sallah informs them that the Nazis have also traveled there using the map. While they are following the trail, the Nazis are ambushed by Kazim and the Brotherhood, but the Nazis manage to kill them all. Henry takes advantage of the distraction to try to rescue Marcus but is captured; Indiana attacks the Nazi convoy in response and is eventually able to destroy it with help from Henry and Marcus while sending Vogel and his tank over the cliff. Indiana, Henry, Marcus, and Sallah proceed to a temple containing the Grail, where they observe the Nazis attempting to overcome the temple's traps before being captured. Donovan forces Indy to find safe passage for them by mortally wounding Henry; a drink from the Grail can heal him. With the help of the diary, Indiana overcomes the traps and finds a room with many cups and an ancient knight, who explains that only one cup is the true Grail. Donovan and Elsa enter the room, and Elsa deliberately gives him the wrong cup, killing Donovan by rapid aging after he drinks from it. Indiana identifies the true Grail and saves Henry's life with a warning from the knight that the Grail can never cross the great seal. Elsa ignores the warning, setting off a cataclysm in the temple; she falls to her death trying to take the Grail, and Indiana nearly suffers the same fate before Henry convinces him to let it go. The Grail falls into an abyss as Indiana and his companions escape and ride off into the sunset.
