"Mistress" is a successful dominatrix with a loyal clientele - and a big problem. She is losing her mean streak. This is very upsetting for her dedicated slave "Boy", who relishes her abusive treatment. Mistress is in a terrible state. She's not only discovering tender feelings for lowly Boy, but she's been hired by a religious cult to train their troupe of self-flagellants for the "aerobics" portion of their new TV show.
