Mr Davis is the first ever male teacher at St. Mary's School for Girls, an establishment which has always subscribed to a strict disciplinary regime, operating a rigid zero tolerance policy in the belief that stamping down heavily on minor infractions prevents more serious problems from developing in the future. He learns that teachers are required to ensure all students' minor infractions are rigorously dealt with... but that teachers are also subject to the same rules and consequences! Ms Frobisher, the tyrannical headmistress, rules staff and pupils alike, and takes great pleasure in delivering stringent corporal correction, as Mr Davis soon finds out. After witnessing a couple of sixth form girls receiving their punishment from the headmistress, he is then expected to help discipline the staff... and rises to the occasion splendidly as he performs his duties!
