Three schoolgirls have been sent to the Matron for discipline. They must sit on the stairwell and each wait their turn for punishment by the Matron who is sitting at the top of the stairs. The first girl called up has never been disciplined at school before, so she receives only an OTK hand spanking. The other two are repeat offenders and they are dealt with more harshly, first being spanked OTK and then bent over the chair for a hard caning. The girls must display their spanked bottoms or watch from the stairs while the others are punished.
