This story is about two college professors from 1890 having a disagreement about the nature of morality. Dr. Anderson argues that it is more important that people be saved and spend eternity with God than that they live good lives; Carlisle agrees but insists that right living is still a good thing by itself. Anderson reveals that he has invented a time machine and seen the future, and he knows how things turn out. He ultimately convinces Carlisle to travel to the future (our present) himself to see. The rest of the movie is about Carlisle’s encounter with 21st century culture and morals.
