The unruly schoolgirls of St Trinian's are more interested in men and mischief than homework and hockey. But greater trouble than ever beckons when the arrival at the school of Princess Fatima of Makyad coincides with the return of recently expelled Arabella Fritton, who has the kidnap of a prize racehorse on her mind. The first film in the classic comedy series.
