Buddies Sid Boggle (Sidney James) and Bernie Lugg (Bernard Bresslaw) take their prudish gal pals (Joan Sims and Dilys Laye) on a camping trip but neglect to mention they're headed to a nudist colony. When a group of buxom schoolgirls arrives on the scene, comic complications ensue in this madcap British gem replete with sexual overtones, sight gags and double entendres. Kenneth Williams plays the girls' pretentious headmaster.
