Fourth entry in the 'Carry On' series. Police Sergeant Wilkins (Sid James, in his 'Carry On' debut) has a new batch of inept recruits on his hands, whose idea of covert surveillance involves dressing up in drag. Bumbling PCs include Kenneth Williams, Charles Hawtrey, Kenneth Connor and Leslie Phillips.

Upper class twit Windrush (Ian Carmichael) causes military mayhem when he joins up in the army. An inept soldier, he unwittingly becomes involved in his high-ranking uncle's (Dennis Price) scam to appropriate some rather valuable spoils of war - a haul of German jewels. A sequel followed with 'I'm Alright Jack'.
