Edinburgh, 1932. The world is on the cusp of change and at the forefront, leading the charge is the estimable Miss Brodie, teacher at the Marcia Blaine School for girls. As a new term begins for Miss Brodie, she is fully prepared. For whatever the subject, Miss Brodie is adept at bringing it around to the experiences girls should look forward to when they too are in their prime.
Meanwhile Miss Brodie's personal life is not so clear cut, torn as she is between the passionate advances of a young married artist, and the more conservative desires of a mature associate, she nevertheless manages to walk a strident path somewhere between the two.
But Miss Brodie's philosophy for living rubs up against the school's rigid moral standards, and when one of her young charges is inspired into a tragic act of foolhardy bravery, an act of almost religious betrayal follows that will shake the firm convictions of Miss Brodie to the core.
