The Belles of St Trinians

The Belles of St Trinian's is a comedy film set in the fictional St Trinian's School, released in 1954. This film and its sequels were inspired by a series of cartoons by British cartoonist Ronald Searle.

St. Trinian's school students became embroiled in a plot with the daughter of an Arab sheik and the sheik's racehorse, trying to gamble on the outcome of the upcoming "Gold Cup" horse race. The Fourth Formers want the sheik's racehorse to win. However, the Sixth Formers want to keep the sheik's racehorse from racing, so that another racehorse can win instead. The headmistress of the school also places a bet on the sheik's racehorse to win, to save her beloved school.

The opposing aims of the two Forms pit the Sixth Form and Fourth Form pupils against each other in a pitched battle, with a general mêlée also involving former pupils.

The sheik's racehorse wins and the headmistress is able to get the school out of debt and reclaim the school's pawned sports trophies with her winnings.
