A disgraced school master, Benjamin Twist, is mistaken for a tough prison governor
and assigned the charge of a prison for particularly hardened criminals. Believing he
is being sent to a school rather than a prison, he celebrates accordingly only to find
that his drunkenness accidently lands him on the wrong side of the prison bars. The
Governorship is eventually restored to him, and he sets about popularising himself
amongst the convicts by turning a blind eye to their shady dealings.
