Stranded (1957)

Rural Minnesota school teacher, Miss Enter (Bette Davis) becomes a courageous survivor during a snow blizzard that leaves her stranded with several students in a 1 room school house 9 miles from the nearest shelter. With a snow plow plodding a course through a snow-packed dirt road that circles the school, at less than 1 mph, Miss Enter cleverly plans an escape route that could lead to their rescue.
