"Come on girls."
Flash (George Cole) is farming the girls out for marriage, and hits on the idea of fixing a schools competition to get the girls over to Italy and an eligible Italian prince. Fearing an imminent international incident the local police plant the hapless police woman Gates (Joyce Grenfell) as an interpreter. Also along for the ride is (Terry-Thomas), who is tricked into supplying the coaches for the trip. Add in a sub-plot about a diamond thief and you have the second installment of the hit comedy, and a fine one at that. Also watch out for Sabrina (the Jordan of her age), as one of the sixth form.
