Schoolgirl learns discipline in detention

The schoolgirl Romy is in detention, since her grades and behavior dropped down lately. So it’s natural for her to be detained and adjusted. She meets Master John who is responsible for troubled girls like her. The plan is to make her obey and she has to do everything John asks, this includes obedience, training, whipping and tickling. Do you think Romy will behave better after her detention ?
