A new school teacher, Arthur Lilley (George C. Scott), and his uppity wife (Anne Meacham) come to Medicine Bow. Arthur is a well-educated man and his wife believes the job beneath him but Arthur sees himself as a coward, thinking he was responsible for the deaths of several students in a fire at his former school in Vermont. When two murderers escape from prison and take as hostages the teacher, his wife and the school children including Betsy Garth, Arthur's mettle meets the supreme test.
