Otto and Spider are trying to crack a safe in what seems to be a mansion. However, they have inadvertently stumbled into an exclusive girls school. The headmistress mistakes them for a visiting professor and newly-hired stable hand. The girls have a plot of their own. They've invited a TV hero to the school - without permission. The action is lively, especially when the headmistress hands Otto the combination to the safe and an envelope containing a thousand dollars.
