Häxan
=== Part 1 ===
A scholarly dissertation on the appearances of demons and witches in primitive and medieval culture, a number of photographs of statuary, paintings, and woodcuts are used as demonstrative pieces. In addition, several large scale models are employed to demonstrate medieval concepts of the structure of the solar system and the commonly accepted depiction of Hell.
=== Part 2 ===
A series of vignettes theatrically demonstrating medieval superstition and beliefs concerning witchcraft, including Satan (played by Christensen himself) tempting a sleeping woman away from her husband's bed and terrorizing a group of monks. Also shown is a woman purchasing a love potion from a supposed witch, and a sequence showing a supposed witch dreaming of flying through the air and attending a witches' gathering.
=== Part 3 ===
A long narrative broken up into several parts; set in the Middle Ages, it concerns an old woman accused of witchcraft by a dying man's family. The narrative is used to demonstrate the treatment of suspected witches by the religious authorities of the time. The old woman, after being tortured, admits to heavy involvement in witchcraft, including detailed descriptions of a Witches' Sabbath, even going so far as to "name" other supposed witches, including two of the women in the dying man's household. Eventually, the dying man's wife is arrested as a witch when one of the clergymen accuses her of bewitching him.
=== Part 4 ===
The final part of the film seeks to demonstrate how the superstitions of old are better understood now. Christensen seeks to make the claim that most who were accused of witchcraft were possibly mentally ill, and in modern times, such behavior is interpreted as a disease. His case revolves around vignettes about a somnambulist and a kleptomaniac, the implication being that these behaviors would have been thought of as demonically-influenced in medieval times whereas modern societies recognize them as psychological ailments. There is heavy irony, however, in the observation that the "temperate shower of the clinic" i.e. the treatment of "hysterical women" in a modern institution, has replaced medieval solutions such as burning at the stake.
