Miss Lucy Pym is a high school teacher of French language who wrote a pop psychology book which, to her surprise, turned out best-seller. She is invited by an old friend, a principle of Leys Physical Training College, to be a guest speaker at this women's facility. Miss Pym is warmly accepted and implored to stay at the college until the day of the demonstration. She becomes interested in the lives and personalities of the college students and their teachers. However, under apparently normal relations Miss Pym detects tension, rivalry and jealousy which eventually lead to an accident. But Miss Pym believes there is more to it.
