Viggo Mortensen and Michael Fassbender star in director David Cronenberg's adaptation of Christopher Hampton's play detailing the deteriorating relationship between Sigmund Freud and Carl Jung as they contend with a particularly troubled patient. The year is 1904. Carl Jung (Fassbender), a disciple of Sigmund Freud (Mortensen), is using Freudian techniques to treat Russian-Jewish psychiatric patient Sabina Spielrein (Keira Knightley) at BurghĂślzli Mental Hospital. But the deeper Jung's relationship with Spielrein grows, the further the burgeoning psychiatrist and his highly respected mentor drift apart.
