Legend has it that one can live forever by drinking water from the Holy Grail used by Jesus at the Last Supper. During a gold mining activity, the stele recording the Holy Grail was discovered. The possibility of the Holy Grail attracted a large number of crazy people to search for it. Dr. Indiana Jones (Harrison Ford) is one of them, and even his father Jones Sr.(Sean Connery) is caught up in it-but he disappears after leaving Jones notes on the Holy Grail. Arriving on the land of Venice, Jones meets with Dr. Sneda (Alison Doody), whom he has made an appointment in advance. After they find the Holy Shield based on clues in the library, they begin to be hunted down by the Crusader Brothers. After some twists and turns, Jones finally found the old Jones. At the same time, Snida's Nazi identity was exposed and his notes were stolen. The Holy Grail could fall into the hands of the Nazis at any time. So, Jones and his son began to jointly stage a wonderful drama of saving the Holy Grail!
