 The headmistress of St Trinian s is jailed, and to try and keep order, the army and the police are called in, they don t stand a chance. This time the hellcats of St. Trinian s want to get to Italy where a rich playboy wants to select one of them as his wife (little does he know what he s letting himself in for). To get to Italy in term time they have to win an essay writing competition, it s easy when you know how. In Europe they run amok and become involved in jewel theft and their normal brand of chaos.
