First in the series of films based on the cartoon creations of Ronald Searle. Miss Millicent Fritton (Alastair Sim), headmistress of St Trinian's School for Girls, attempts to stave off her creditors by 'looking after' the pocket money of a wealthy sheikh's daughter currently enrolled at the school, and investing it on the sheikh's horse, Arab Boy, in the local derby. Unfortunately, Miss Fritton's bookmaking brother Clarence (also Sim) has backed another horse, and kidnaps Arab Boy to ensure his own sizeable win. Miss Fritton enlists the help of disreputable boot boy Flash Harry (George Cole), the teaching staff and the Old Girls in rescuing Arab Boy and returning him to the race.

Four films based on the cartoon creations of Ronald Searle. In 'The Belles of St Trinians' (1954), Miss Millicent Fritton (Alastair Sim), headmistress of St Trinian's School for Girls, attempts to stave off her creditors by 'looking after' the pocket money of a wealthy sheikh's daughter currently enrolled at the school, and investing it on the sheikh's horse, Arab Boy, in the local derby. In 'Blue Murder at St Trinians' (1956), the anarchic schoolgirls win a UNESCO prize trip to Rome. Upon arrival they become involved with a jewel thief (Lionel Jeffries) who hides out with the school, disguised as the headmistress. The jolly hockey sticks are being waved with malicious force once again in 'The Pure Hell of St Trinians' (1957). After they burn their school down, the girls are sent to the Middle East, where an Arab sheik tries to lure them into his harem. Flash Harry (George Cole) attempts to come to the rescue, only to find himself stranded on a desert island with a familiar member of the constabulary (Joyce Grenfell). In the 1966 film 'The Great St Trinians Train Robbery', a bunch of crooks take on more than they can handle when they decide to bury the loot from a successful robbery in the grounds of St Trinians. The high-spirited girls (or 'hooligans' as they are sometimes known) take it upon themselves to confront the highly-strung criminals, with devastating and comic effect.

Horror anthology. Architect Walter Craig (Mervyn Johns) arrives at country house Pilgrim Farm thinking that he has been hired to remodel it. He finds the building strangely familiar, and upon entering discovers that he recognizes all of the house's occupants from a recurring nightmare he has experienced. One by one, everyone present relates their own horrific nightmare: Grainger (Anthony Baird) dreams that he is a racing driver recuperating from an accident; teenager Sally O'Hara (Sally Ann Howes) dreams of a Christmas party where she discovers a lone crying child; Joan Courtland (Googie Withers) relates a story of an antique mirror linked to an ancient murder; the next story concerns two golfers who vie murderously for the attention of a young lady; and the final story features a ventriloquist (Michael Redgrave) whose dummy comes to life.
