CARNIVAL OF SOULS

In Kansas, Mary Henry is riding in a car with two other young women when two men challenge them to a road race. During the race, the women's car is nudged by the boys' car and plunges off a bridge into a muddy river. Three hours after the police start dredging the water to look for them, Mary miraculously surfaces on the river bank, but cannot remember how she survived.

Mary moves to Salt Lake City, where she has been hired as a church organist. While driving near an abandoned pavilion on the shores of the Great Salt Lake, Mary begins experiencing visions of a ghoulish, pale-faced figure (referred to as "The Man" in the credits). A gas station attendant tells her the pavilion was first a bathhouse, then a dance hall, and finally a carnival before it was abandoned. In town, Mary rents a room and visits the church where she will be playing the organ. Mary takes a ride out to the pavilion at the lake with the church's minister who stops her from entering, warning that it is against the law.

Mary continues experiencing visions of The Man and also rejects the repeated advances of John, a socially awkward neighboring lodger. Mary goes to the pavilion by herself to investigate but does not find anything. Later, Mary begins experiencing terrifying interludes when she becomes invisible and inaudible to the rest of the world. During one of these episodes, Mary meets Dr. Samuels, who offers to help her while acknowledging he is not a psychiatrist. Mary returns to the church by herself to practice the organ and finds herself shifting from a hymn to eerie music. In a trance, she sees visions of The Man and other ghouls dancing at the pavilion. The minister, hearing the strange music, denounces it as sacrilege and insists that Mary resign.

That night, Mary accompanies John to a bar. Terrified of being alone with her nightmares, Mary tells John she wants his company, although he has little sympathy for her obvious distress and is only interested in sleeping with her. When they return home, John tries to convince Mary to let him stay the night; however, Mary becomes hysterical when she sees The Man in the mirror. John leaves, believing Mary to be insane. The following morning, after moving out of the boarding house, Mary returns to the pavilion where she encounters The Man and his fellow ghouls. She tries frantically to escape, but the locals do not acknowledge her and she only encounters more ghouls until she wakes up, revealing the previous scene to be merely a nightmare. She is later drawn back to the pavilion once again, where she finds the ghouls dancing, with a ghoul version of herself paired with The Man. She tries to run away but is chased by the ghouls onto the beach, where she collapses as they close in.

The following day, Dr. Samuels, the minister, and the police go to the pavilion to look for Mary. They find her footprints but note that she has otherwise vanished. Back in Kansas, the submerged car is finally pulled from the river. Mary's body is seen in the front seat alongside the other two women.

Mary is ultimately claimed by the ghouls at the abandoned pavilion; her body is later found in the car wreckage, revealing she never truly survived the accident.

The film’s ending recontextualizes Mary’s ordeal as a liminal journey between life and death, with her visions and isolation explained by her own status as one of the dead. Her haunting was not just psychological trauma but a supernatural claim—solidifying Carnival of Souls as a bleak meditation on fate, mortality, and the impossibility of escape.
