Blue Murder at St. Trinian's

When the students of St. Trinian's, an all-girl preparatory school, see their school commandeered by police forces, the devilish girls find ways to turn the situation into bedlam. Soon afterward, they cheat their way to a European trip, accompanied by driver Capt. Carlton-Ricketts (Terry-Thomas), where the girls are caught up in a diamond theft. At the same time, Flash Harry (George Cole) has been trying to get some of the older girls married to wealthy and powerful men.
