Agent Sadusky tracks Ben to the Library and the three narrowly escape capture.
Ben, Riley, Abigail, and Patrick then head to Mount Rushmore, where they meet Mitch, who has kidnapped Ben's mother, Emily. Mitch helps them find the entrance of a cave, containing the legendary Native American city of gold, Cíbola. Once inside, they encounter several traps and everyone gets separated. Eventually, they find the city of solid gold underneath Mount Rushmore and it begins flooding with water. In order to get out alive, one person has to stay behind to hold open the door to the tunnel. After a struggle and Ben's attempt to sacrifice himself, Mitch ends up staying behind and asking Ben to give him the credit for finding the treasure.
