Eleventh entry in the 'Carry On' series. Marshall P. Knutt (Jim Dale), a former sanitary engineer, becomes the sheriff of Stodge City in the Wild West and must help a young woman beat the Rumpo Kid (Sid James), the outlaw who shot her father. Those getting off their horses and drinking their milk include Kenneth Williams, Charles Hawtrey, Joan Sims and Bernard Bresslaw (making his 'Carry On' debut).

'60s B-Movie Caper featuring a jungle guide (Michael Latimer) kidnapped by a lost tribe of natives who want to sacrifice him to their god - a white rhino. At the moment of his imminent dispatch, however, he is incredibly thrown backwards in time to a kingdom of dominant, uniformly buxom and comely brunette ladies and their blonde slaves. Their leader Queen Kari (Martine Beswick) puts the hard word on the junglist but he turns her down and sides with the blondes, leading to his imprisonment. Escape from the shoddily built prison looks simple enough, but then there's the matter of escaping this prehistoric timeslice and getting back to the '60s.Produced under the title 'Slave Girls of the White Rhino', the film was a hastily conceived means of recycling the sets and costumes from One Million Years B.C. Producer and director Michael Carreras wisely wrote the screenplay under a pseudonym. The name he chose, 'Henry Younger', was a joke at the expense of Anthony Hinds, who wrote under the name 'John Elder'.
