It is a one act play set in a school with three characters: Taplow, Frank, and Mr. Crocker Harris. Mr. Crocker Harris is a middle-aged schoolmaster, Taplow is a sixteen year old student, Frank is a young teacher, and Mr. Crocker Harris is a sixteen-year-old student. Taplow has arrived at school to assist Mr. Crocker Harris with some extra work. While Taplow needs to wait for Mr. Harris, he meets Frank and they have a conversation. Later, Millie, Mrs. Crocker Harris, enters and speaks with Taplow.
