Classic British farce about a girls' school where the students are delinquents-in-training, the headmistress is senile and sometimes tipsy, and her brother wants to use the school as a front for his book-making ring. Alastair Sim plays the sibling rivals; with George Cole, Beryl Reid, Joan Sims.

The arrival of Sultan's daughter Princess Fatima at England's famous and prestigious 'School for Young Ladies' precipitates even more chaos than usual. Her father's horse Arab Boy is due to run at the nearby Gold Cup so Clarence Fitton, bookie brother of headmistress Millicent, ensures his own daughter is on hand to report progress. At the same time Barchester police have planted sergeant Ruby Gates as a teacher, and the Ministry of Education are sending a third inspector down after the previous two disappeared without trace.
