Description
In Kansas, Mary Henry is riding in a car with two other young women when two men challenge them to a drag race. During the race, the women's car plunges off a bridge into a river. Three hours after the police start dredging the water to look for them, Mary miraculously surfaces on land, but cannot remember how she survived.
Mary moves to Salt Lake City, where she has been hired as a church organist. While driving through the desert, Mary's radio starts playing nothing but strange organ music, and she has visions of a ghoulish, pasty-faced figure (simply called "The Man" in dialogue). She also sees a large, abandoned pavilion on the shores of the Great Salt Lake. A gas station attendant tells her the pavilion was first a bathhouse, then a dance hall, and finally a carnival before it closed.
In town, Mary rents a room. She meets the proprietor who informs there is another lodger staying there. Mary unpacks her suitcase and goes to the church where she will be playing the organ. At the Church she meets the minister and plays the organ for the first time. At the minister's offer, Mary takes a ride out to the pavilion at the lake. She is stopped from entering by the minister who warns her that to enter would be illegal.
When she returns to her lodgings Mary meets a man, John, the only other lodger, who wants to become better acquainted. Mary however, retreats as she is not interested. That night, she becomes upset when she sees The Man downstairs and retreats to her room. Soon, Mary begins experiencing terrifying interludes when she becomes invisible and inaudible to the rest of the world, as if she simply is not there. When The Man appears briefly in front of her in a park, she flees, right into the arms of a Dr. Samuels. He tries to help her, acknowledging he is not a psychiatrist.
Mary's new employer, the minister (Art Ellison), is put off when she declines a reception to meet the congregation. When she practices for the first time, she finds herself shifting from a hymn to eerie music. In a trance, she sees The Man and other ghouls dancing at the pavilion. The minister, hearing the strange music, denounces it as sacrilege and insists upon her resignation.
Terrified of being alone, Mary agrees to go out on a date with John. When they return home, he follows her to her bedroom door. John tries to convince Mary to let him stay the night, but she walks away, apparently uninterested. Nevertheless, he follows her to her bedroom, where she sees The Man in the mirror. Frightened, she tells John what has been happening to her. He leaves, believing she is losing her mind.
After going back to Samuels' office, Mary believes she has to go to the pavilion. However, Mary is confronted by The Man and his fellow ghouls. She tries frantically to escape, boarding a bus to leave town, only to find that all the passengers are ghouls.
It is just a nightmare; she awakes in her car. In the end, she is drawn back to the pavilion, where she finds her tormentors dancing, a pale version of herself paired with The Man. When she runs away, the ghouls chase her onto the beach. She collapses as they close in.
The following day, Samuels, the minister, and police go to the pavilion to look for Mary. They find her footprints in the sand and they end abruptly. Back in Kansas, her car is pulled from the river. Mary's body is in the front seat alongside the other two women.
While driving her car with two girlfriends, the driver is challenge to a drag race and falls off a bridge over a river. When it seems that the girls have drowned and there are no survivors, Mary Henry surprisingly get's out of the water. A couple of days later, she drives to another town to work as organist in a church despite not being religious. While driving, she has visions of weird people. When she arrives, she moves into a room of the house owned by Mrs. Thomas. However Mary is haunted by spirits and is frequently drawn to a nearby abandoned carnival, where she discloses a dark secret.
