During World War II, an American paratrooper on a covert mission drops into eastern France to find mystery, romance, murder, espionage and becomes involved with the Prieure de Sion, an ancient secret order that has been quietly influencing western society for centuries. And that is only the beginning. For over a thousand years, members of the Prieure de Sion have been the targets of assassinations. Why? The tale weaves a thread that begins in the alpine meadows of the Jura mountains, and moves into mystical journeys of self-realization in the labyrinth and secret underground temple complex near Rennes le Chateau in southwestern France."
