In early-20th-century Switzerland, Carl Jung (Fassbender), disciple of father of psychotherapy Sigmund Freud (Mortensen), is seduced by the challenge of an impossible case to treat a seriously disturbed young woman, Sabina (Knightley). She is highly intelligent and hopes to be a doctor, eventually becoming a psychiatrist in her own right. The married Jung and Sabina eventually become lovers. Jung and Freud develop an almost father-son relationship; with Freud seeing the young Jung as his likely successor as the standard-bearer of his beliefs. But, as their relationship becomes dangerously intimate, Jung begins to wonder whether Freud's theories aren't fatally flawed.
