When our boys were young, they loved the Indiana Jones movies. In the third movie of the series, titled Indiana Jones and the Last Crusade, Harrison Ford’s character searched for the cup Jesus used at the Last Supper. He was searching for the cup (named in legend as the Holy Grail) because it supposedly had power to not only heal, but also give eternal life to those who drink from it. As he looked for it, he discovered that the Germans were also trying to find it so they could use its power to win the war. Following clues his father had collected, battling villains who wanted to use the cup for evil purposes, and guardians who wanted to prevent anyone from finding it, Indy finally ended up in a cave in the desert.
