Mistress is critiquing graduation day for two of her want-a-be dominatrixes. Their final test is how they handle a submissive named Cinderella, but it's soon apparent to the Mistress that applicant Patti is under performing badly. She's immediately punished for her inadequate job in training Cinderella who, as further humiliation gets to watch her ordeal.

Denise, the remaining want-to-be, confesses she probably wouldn't do any better, and the Mistress quickly removes this applicant to her private chamber for further motivation.

Cinderella is also subjected to various torments in the chamber, but she withstands her ordeal so courageously (much better than Patti or Denise) that the Mistress tells her she has the makings of a true mistress. No more Cinderella, from now on she'll be called Cindy.
