Old Lady Ironsides - S3.E12

A high school senior is denied the chance to finish two more months of high school for a diploma, just because she has been found to be pregnant. A little old lady who has befriended the girl, and who had been an active Suffragette, determines to help her: she chains herself to the school entrance. The attending publicity and subsequent sanity hearing for the old lady, force the board to change its ruling.
