On April 15, 1912--ironically the very date on which more than a thousand people lost their lives as the Titanic sank--a figure known only as Pilgrim tries to commit suicide by hanging himself from a tree. When he is found five hours later, his heart miraculously begins beating again. This isn't his first attempt to end his life, and it is decided that steps must be taken to prevent Pilgrim from doing himself further harm. Escorted by his beloved friend, Lady Sybil Quartermaine, Pilgrim is admitted to the famous Burgholzi Psychiatric Clinic in Zurich, where he will begin a battle of psyche and soul with Carl Jung, the self-professed mystical scientist of the unconscious--who is also a slave to his own sexual appetites.
