A Naughty British Nanny makes her debut in the third installment of The Karen Carpenter Mysteries. In this movie we get to see that back in the 40s, when nanny's apprentice son returns home from an all-too-short vacation and tells his mother that his father is a filthy pervert. The pervert, of course, is none other than Mrs. Lovett, a former beauty queen. The once charming and caring mother, now bitter and vindictive, sets about to punish her son for bringing shame to her own name...and of course to the entire family. A horny, drunken, and well-hung blonde stands at the head of the family, dominating the relationship until finally her son storms out of the house in a huff and tells his mistress that she's going to be expecting a visit from his "new boss"...the much-older Naughty British nanny!.
