Blue Murder at St. Trinian's

“They're back... and up to no good!!!”

It is 1957, and St Trinian's has lost its headmistress, Miss Fritton (Alastair Sim), to her majesty's prison. The army steps in to mind the girls, led by Captain Romney Carlton-Ricketts (Terry-Thomas), who has no idea what he has taken on. Frank Launder sends the sixth form scheming for a trip to Italy, and Europe's relations hang on whether anyone can stop them.
