When they meet in New York in 1925, Henry Murray is an ambitious physician from Harvard who is married to a rich woman from Boston, and Christiana Morgan is an upsetting art student married to a war veteran. Attracted to each other by a force they cannot explain, they both travel to Switzerland to meet with Carl Jung; Christiana is then submitted to intense sessions of hypnosis. The woman's visions are soon part of an experiment that pursues a deep love affair that would last for forty-two years.
