Rated "X" upon its initial release in 1970, End of the Road would probably rate at most a hard "R" today. Stacy Keach stars as Jake Horner, a college professor beset with a wide variety of emotional problems. He seeks out help in therapy, conducted by unorthodox psychologist Dr. D (James Earl Jones). This treatment turns out to have a disastrous effect on Horner, leading him into the arms of Rennie Morgan (Dorothy Tristan), the wife of a fellow teacher. End of the Road was adapted from a story by John Barth.
