In one of the best of the long-running Carry On series, Western clichés are run through the Carry-On wringer. The film takes place in wild and woolly Stodge City, a town held in thrall to the nasty dealings of The Rumpo Kid (Sidney James). The Rumpo Kid holds the town in such abject terror that Judge Burke (Kenneth Williams) compels Sheriff Albert Earp (Jon Pertwee) to run The Rumpo Kid out of town. But when Earp confronts The Rumpo Kid, Earp is shot dead for his troubles. Burke puts out a call for a new lawman for the town and, due to a series of misunderstandings, an English custodian, Marshall P. Knutt (Jim Dale) is hired for the job. Arriving at the same time as Knutt is Annie Oakley (Angela Douglas), who has come to town to get vengeance for her father's murder (her father being the deceased sheriff). Events simmer and boil to a final confrontation between The Rumpo Kid and Nutt, who utilizes his custodial skills to defeat The Rumpo Kid and his evil gang.
