The Touch of Satan is a 1971 American independent horror film directed by Don Henderson and starring Michael Berry and Emby Mellay in their debut roles.
The film was shot between 1968 and 1970 in the Santa Ynez, California area and featured early work by movie makeup artist Joe Blasco, cinematographer Jordan Cronenweth, and composer Robert O. Ragland.
The scene then switches to the main character, a young man named Jodie who is on an open-ended car trip across America to find himself and discover whether or not he wishes to follow in his father's footsteps as a lawyer.
Melissa was given eternal life and youth as a result of this bargain, but the gift was a curse as she watched her now-insane sister grow old and homicidal.
The movie ends with the realization that each are bound to Satan and that Melissa's attempt to save herself has only managed to draw Jodie into the evil contract as well.
