After finding the "Rose Key" in a cave in Iran which she narrowly escapes as it collapses, she travels to Paris, where she then enlists the help of George, her former lover. Along with Benji the cameraman, they translate Flamel's headstone, which contains a riddle that leads them 370 feet underneath the streets of Paris. She enlists the help of a guide called Papillon, his girlfriend Souxie, and friend Zed to search the Catacombs of Paris.
